Missouri 2005 Bianca Piper Cold Case Finally Solved — FULL DETAILS
First at 6:00, the new push to solve one of the St. Louis area’s most troubling missing persons cases. 13-year-old Bianca Piper disappeared without a trace two decades ago.
“It was the evening of March 10th, 2005. Snow was falling on a rural road in Foley, Missouri, a stretch of McIntosh Hill Road that on most nights carries almost no traffic. A 13-year-old girl has just been dropped off there, approximately 1 mile from home, carrying a flashlight. She is wearing a lime green blouse, a gray Adidas hooded sweatshirt, blue jeans, and white tennis sneakers. It is getting dark. The temperature is falling below freezing.”
Her mother watches her begin to walk, then turns the car around and drives back to the house to start dinner. The girl never arrives home.
What happened on that road, in that snow, on that specific evening in early March has never been publicly established. Twenty years later, the Amber Alert issued for Bianca Noelle Piper remains active. No remains have ever been recovered. No person has ever been charged in connection with her disappearance. And no one—not investigators, not courts, not the family that has spent two decades searching—knows with documented certainty what took place after Bianca Piper stepped out of her mother’s car on McIntosh Hill Road.
This is the story of what is known. It is a story about the distance between a child leaving a car and a child not arriving home, a distance of less than 1 mile, across which an entire life disappeared.
Foley, Missouri, sits in Lincoln County, roughly an hour’s drive northwest of St. Louis. According to the 2000 United States Census, the population of Foley at the time of Bianca’s disappearance was approximately 175 people. It is a small rural community, the kind of place defined not by landmarks but by the absence of them. The roads that run through it are not well-traveled after dark. The landscape around it is largely agricultural, broken up by stretches of woodland and brush.
McIntosh Hill Road, where Bianca was last seen, is not a major thoroughfare. It is the kind of road that only people who live nearby have reason to use. Lincoln County itself, the county that encompasses Foley, had a population of around 44,000 at the time. Its county seat is Troy, roughly 10 miles distant. The Lincoln County Sheriff’s Department covers the unincorporated areas of the county, including the rural stretch of road where Bianca walked on the night she disappeared. For most of the two decades that followed her disappearance, it has been the primary agency responsible for the investigation.
The Piper family moved to Foley in October of 2004, approximately 5 months before Bianca disappeared. Prior to that move, Shannon Tanner, Bianca’s mother, had been living with her daughters in Troy. Shannon had been dating a man named Jim Felt, and when Jim moved in with the family in October of 2004, the household relocated to Foley, specifically to a home on McIntosh Hill Road. The road that became the last confirmed location of Bianca’s life was, in the months before her disappearance, the road where she lived.
If you have ever lived in a small rural community, visited one, or driven through one at night, you understand something about what the phrase “not a well-traveled road” actually means after dark. It means almost no one passes. It means a child walking in the dark, in the snow, with a flashlight would be almost invisible to the larger world. It means that whatever happened on McIntosh Hill Road on the evening of March 10th, 2005, happened in a place where the chance of a witness was very low. Our community understands the geography of vulnerability. It does not always announce itself. Sometimes it is just a quiet road after dark in winter.
Bianca Noelle Piper was born on December 26th, 1991, in Foley, Missouri. She was the youngest of three daughters born to Shannon Tanner and David Piper. Her parents divorced in 1993 when Bianca was still an infant. After the divorce, David Piper moved to Fredericktown, Missouri, where he worked as a truck driver. Shannon Tanner remained the primary custodial parent of the three girls.
According to the Charley Project, a non-profit database of missing persons cases that maintains one of the most thoroughly sourced public files on Bianca’s disappearance, Bianca had been in therapy since the age of four. She was diagnosed with attention deficit hyperactivity disorder and severe bipolar disorder. These diagnoses were not peripheral to her daily life. They shaped it in documented, specific ways.
She required daily prescription medications. When she took those medications consistently and on schedule, her conditions were, according to family accounts and the Charley Project’s documentation, manageable. When she missed doses, when the medications did not arrive in her system when they were supposed to, she could become disoriented. The Charley Project notes that in that state, she was documented to experience hallucinations.
These are not details included here to define Bianca by her diagnosis. They are included because they are part of the documented factual record of her disappearance. They informed the therapeutic strategy that placed her on that road. They informed the question of what she was capable of on the night she disappeared, and they are part of what investigators have had to consider for 20 years.
At the time of her disappearance, Bianca was 13 years old and enrolled in the eighth grade at Winfield Middle School in Winfield, Missouri, a school in the neighboring community. She was in special education classes, a placement that reflected both her documented short attention span and the significant absences from school that her psychiatric conditions had caused over the years. Her teachers, according to the Charley Project’s documentation, described her as artistically talented.
The physical description released by law enforcement in connection with Bianca’s missing persons report placed her at 5 ft 6 in tall, weighing approximately 185 lbs. She had brown hair and brown eyes. She was 13 years old on the evening she disappeared. 13 years old, in street clothes, in falling snow, carrying a flashlight on a rural Missouri road.
Confirmed accounts of Bianca’s personality and interests come from family members who have spoken publicly in the years since her disappearance. Her sister, Tiffany Piper, speaking to KSDK in St. Louis in March of 2018 on the 13th anniversary of the disappearance, recalled that Bianca was passionate about singing and that she was, in Tiffany’s own words, a “fashionista.” The Lincoln County Journal’s September 2005 coverage published additional recollections from Tiffany that Bianca loved horses, Barbie, and the color purple, and that she had wanted to become a singer. Her teachers at Winfield Middle School confirmed she was artistically talented. These details form the publicly documented picture of who Bianca was.
One detail from the documented record deserves particular attention in the context of what happened the following day. According to accounts compiled in multiple sources on the case, including coverage attributed to the Springfield News-Leader on March 9th, 2005, the day before her disappearance, Shannon Tanner returned home from work to find Bianca with her bags packed. The public record does not fully clarify what Bianca intended by packing her bags on March 9th or what happened after that. What it does establish is that the day before Bianca disappeared, something was unsettled in the house.
These are the confirmed biographical details available in the public record. Much about Bianca’s specific daily life, her friendships, her school experience beyond what teachers confirmed, the texture of her days has not been publicly documented or officially confirmed. What is known is what her family has shared and what investigators placed on the record. The rest belongs to memory and to the people who knew her.
Our community understands this—the way the public record of a missing child can feel thin against the fullness of the life that was actually lived. Bianca Piper had a favorite color. She had things she argued about, things she loved, a voice she was going to use to sing. The documents know only the edges of all of that. The rest lives in the people who knew her and who have carried her absence for more than 20 years.
The family at the center of this case consists of several confirmed individuals whose identities, relationships, and roles are part of the documented public record. Shannon Tanner is Bianca’s mother. She is the person who dropped Bianca off on McIntosh Hill Road on the evening of March 10th, 2005, and who reported her missing at 8:20 that night. Shannon has given multiple interviews to the media over the years—to Fox 2 in St. Louis, to the St. Louis Post-Dispatch, and to other outlets—and her statements form the primary first-person account of the circumstances surrounding Bianca’s disappearance.
In a 2019 interview with Fox 2, Shannon described that evening in her own words: “I dropped her off and told her I’d see her in a few minutes. I went home and started cooking dinner and then in 10 or 15 minutes when she hadn’t returned, we went looking for her and she was gone without a trace.”
Shannon also acknowledged in that same interview and in others that she had received criticism for allowing Bianca to be dropped off that way. She described understanding why that criticism came. She said she still hears from people who see Bianca’s photo posted around town and that it gives her hope. Hope that someone is still looking. In an interview with the St. Louis Post-Dispatch, Shannon stated that she drove back toward the drop-off point to warn Bianca not to accept a ride from a stranger. In that same interview, as documented in multiple secondary sources that cite the Post-Dispatch reporting, Shannon said, “I wish now I told her I love her.”
Shannon Tanner has never been named a suspect in Bianca’s disappearance. She was questioned extensively and administered a polygraph test, which she passed. The Lincoln County Sheriff’s Department has repeatedly and publicly stated that no family members are considered suspects. Jim Felt, Shannon’s live-in boyfriend at the time of the disappearance, was also questioned at length and administered a polygraph test. He passed. Investigators have not named him a suspect.
David Piper, Bianca’s biological father, was also extensively interviewed. He too was cleared. He had been living in Fredericktown, Missouri, working as a truck driver at the time of his youngest daughter’s disappearance. He died in 2009 at the age of 51 from a heart attack without ever having learned what happened to Bianca.
Tiffany Piper is Bianca’s older sister, born approximately 18 months before her. On the day Bianca disappeared, Tiffany had come home from spending time with a friend after school. She gave a documented public account of that afternoon to the Lincoln County Journal in September of 2005: “I didn’t know it at the time, but the day turned into a nightmare. I came home from hanging out with a friend after school. Bianca was home by herself. She was in the living room singing karaoke and I laid on the couch and dozed off. When I woke up, my mom and her boyfriend had gotten home from work. We were to do our chores and preparing for dinner. Bianca was going for a walk instead.”
Tiffany’s statement to KSDK in 2018 contains one detail that has been widely noted in coverage of this case: “The last thing that I said to her was, ‘Thanks a lot. I’m going to have to finish up your chores now.’ And it seems silly, but still 13 years later, that’s what I…” She did not complete the sentence in the published account. What she left unsaid in that moment is not something the public record can fill.
Among the investigators who have spoken publicly on the case, Lincoln County Chief Deputy Wade O’Herron and former Lincoln County Sheriff Rick Harrell have been the most prominent named officials. Their statements to media and to the Lincoln County Journal constitute significant portions of the official record that is publicly available.
The evening of March 10th, 2005, begins in a way that investigators and family accounts describe as consistent with an established pattern, not as an unusual or isolated event. According to the Charley Project’s documented file and multiple law enforcement statements, Bianca’s therapist had at some prior point recommended a specific behavioral strategy for managing her frustration and anger: Shannon would drive Bianca a short distance from home and allow her to walk back on her own. The walk was intended to give Bianca time and physical space to decompress.
Lincoln County Chief Deputy Wade O’Herron confirmed this detail publicly in his September 2005 statement to First Alert 4. Walking alone for a short period of time was suggested by multiple therapists as a way to help Bianca manage her frustration. The strategy had been used before March 10th. According to the Charley Project, it had been attempted once prior to the night of Bianca’s disappearance and Bianca had found it genuinely helpful.
On the evening of March 10th, Bianca had gotten into a dispute with her mother over the household chore of washing the dinner dishes. What the public record establishes is that Bianca, not her mother, requested the walk. She asked to be dropped off and she asked specifically to be dropped off at a greater distance from home than she had been before. That detail matters. Shannon Tanner did not impose the walk as a punishment. Bianca asked for it. The therapeutic strategy had worked before.
That night, following what had been confirmed as helpful prior practice, Shannon Tanner drove her daughter to McIntosh Hill Road. The drop-off point was near a bridge on that road, approximately 1 mile from their home. Shannon Tanner confirmed in her public interviews that Bianca was dropped off at around 6:15 in the evening. It was snowing. Darkness was falling. Bianca had her flashlight.
Shannon then drove home and began preparing dinner. Within approximately 10 to 15 minutes by Shannon’s own account, Bianca had not returned. Shannon drove back. According to reporting in the Springfield News-Leader, she knocked on doors at nearby homes, asking neighbors if they had seen her daughter. No one had. Shannon reported her daughter missing at 8:20 that evening. From the moment she stepped out of that car on McIntosh Hill Road, Bianca Noelle Piper was never seen again by anyone who has since come forward.
Our community understands what it means to hold a decision in your hands for the rest of your life, to replay a moment, to ask whether a different choice would have changed what came next. Shannon Tanner dropped her daughter off on a road and drove home. She was following guidance that had previously helped. 10 minutes later, her daughter was gone. The decision itself and its consequences are documented facts. What they mean to the person who made them, that is something only Shannon Tanner can know.
The Lincoln County Sheriff’s Department responded to the missing person’s report on the night of March 10th. The initial assessment, as investigators have documented, was that Bianca may simply have become lost on her way home. This was not an unreasonable initial conclusion. The terrain around Foley is rural. There is brush and woodland along the roadsides. In the dark and snow of that March evening, with temperatures dropping below freezing, a child who became disoriented could be in serious danger quickly. Investigators began the search as if Bianca might still be found alive and nearby. That possibility did not hold for long.
The search that followed was by any measure extensive. According to documented accounts from the Lincoln County Sheriff’s Department and from media coverage, the search included dozens of volunteers from Foley and surrounding communities, trained law enforcement personnel from multiple agencies, search dogs, horseback riders, four-wheelers to cover rough terrain, and helicopter coverage from the air. The area searched, according to documented reports, covered approximately 270 square miles. No trace of Bianca was found. KSDK reported in 2018 that there had been a couple of false alarms during the search—moments when searchers believed they might have located something significant—but none produced any confirmed evidence of Bianca’s location.
The Charley Project notes that investigators specifically observed that Bianca had no documented history of running away from home. She had not taken any belongings beyond the flashlight that her mother had given her. There was no confirmed indication from family or school that she had expressed any intent to leave. These factors, combined with the complete failure of the extensive physical search to locate any trace of her in a defined geographic area, starting almost immediately after she was reported missing, led investigators to conclude that Bianca had most likely been abducted.
The Amber Alert for Bianca Noelle Piper was issued through official channels. It carried her confirmed description: Height, 5 ft 6 in; weight, approximately 185 lbs; brown hair; brown eyes; age 13. It documented her clothing: the lime green blouse, the gray Adidas hooded sweatshirt, the blue jeans, the white tennis sneakers. And it documented the last confirmed information about her location: McIntosh Hill Road, Foley, Missouri, approximately 6:15 in the evening on March 10th, 2005. As of January of 2026, per the National Center for Missing and Exploited Children’s published documentation, that Amber Alert had not been canceled. It remains active.
In the weeks and months following Bianca’s disappearance, the investigation pursued multiple avenues and produced no physical evidence, no confirmed witness, and no named suspect. The road where Bianca had been walking was searched thoroughly and repeatedly. The area around the bridge where Shannon dropped her off received particular attention. Nothing was recovered that could be confirmed as connected to her disappearance.
The Charley Project notes that the “lost to exposure” theory—that Bianca had wandered off the road in the dark and cold and succumbed to the elements—was considered carefully in the early stages of the investigation. Given the temperatures that night, the documented risk of disorientation when her medications were not taken on schedule, and the darkness, it was not an implausible early hypothesis. But the search was conducted thoroughly by trained personnel and dogs across a wide area. No remains were found. Over time, investigators moved away from that theory.
The investigation examined the people closest to Bianca. Shannon Tanner and Jim Felt were questioned for several hours, and both were administered polygraph tests. Both passed. David Piper, Bianca’s father, was also extensively interviewed and cleared. As has been confirmed by the Lincoln County Sheriff’s Department in multiple public statements across multiple years, no family members are considered suspects in this case.
In May of 2005, approximately 2 months after Bianca’s disappearance, police received a report of a domestic dispute between Shannon Tanner and Jim Felt. Shannon filed a complaint, and the couple subsequently reconciled. Shannon withdrew the complaint. Investigators stated publicly that this incident had no bearing on the Piper investigation.
In June of 2005, roughly 3 months after Bianca went missing, police responded again to Shannon Tanner’s residence. The St. Louis Post-Dispatch reported on the incident. Shannon was arrested on a domestic assault charge in connection with an altercation with another daughter. The details of that incident, including Shannon’s account and the account of the daughter, were reported by the Post-Dispatch and are part of the public record. Shannon was released after posting bail. Investigators publicly maintained that this arrest did not change their assessment of Shannon Tanner’s status in connection with Bianca’s disappearance. She has never been named a suspect.
Local registered sex offenders in the area were investigated and interviewed. Their residences were searched. No connection to Bianca’s disappearance was established. The family had offered a $5,000 reward for information. As documented in a 2007 Associated Press report published in the Nevada Daily Mail, investigators continued to seek tips and had not ruled anything out, but the case had, in the words of Lincoln County investigator Rick Harrell, as reported in that period, “pretty much broken down to nothing” in terms of actionable leads.
Our community understands what it means when an investigation reaches a wall, not because the investigators stopped caring or stopped working, but because the physical record simply is not there. You cannot charge someone without evidence. You cannot solve a case on grief alone, no matter how much grief there is. What the Lincoln County Sheriff’s Department faced after the extensive initial search produced nothing was not a failure of will. It was the documented reality of an investigation without physical evidence, and that reality is one of the most difficult things in law enforcement. A case you know matters, a family you know is suffering, and a record that will not yield what you need.
In January of 2007, nearly 2 years after Bianca’s disappearance, the investigation entered a new phase, one that generated significant national attention and a concentrated investigative effort. On January 12th, 2007, a man named Michael J. Devlin was arrested in Kirkwood, Missouri, after two missing boys were discovered alive in his apartment. The boys were 15-year-old Shawn Hornbeck and 13-year-old Ben Ownby. Hornbeck had been abducted in 2002 from Richwoods, Missouri, and had been missing for more than 4 years. Ownby had been abducted from Beaufort, Missouri, just 4 days before Devlin’s arrest. Both had been held against their will. Devlin subsequently pleaded guilty to kidnapping and child molestation charges. He was sentenced to life in prison.
The discovery of two boys alive in an abductor’s apartment in St. Louis County, one of whom had been missing for years, prompted investigators across Missouri to ask whether Devlin might be connected to other missing children in the region. A multi-jurisdictional task force involving federal, state, and local law enforcement was created specifically to investigate that question. The task force examined Devlin’s possible connection to Bianca Piper’s case, as well as to the 1988 disappearance of 9-year-old Scott Alan Kleeschulte, and the 1991 disappearance of 11-year-old Charles Arlin Henderson.
A Lincoln County detective made a documented statement about Devlin’s awareness of the Piper search, as cited in coverage from that period and documented in the Wikipedia article on Bianca’s disappearance. The detective stated, “Whether he was a part of it, in it, or in the middle, or just watching from afar, he absolutely knew what was going on. I certainly believe Michael Devlin was monitoring our search and the disappearance of Bianca Piper.” That statement was not a finding. It was a belief stated publicly by an investigator, and it reflected the thinking of the task force at that time.
The task force pursued that line of inquiry for approximately 9 months. In October of 2007, the task force was formally dissolved. It had found no evidence connecting Devlin to Bianca Piper’s disappearance, nor to the disappearances of any other children in the region. Devlin himself was never charged in connection with Bianca’s case. No evidentiary link between them has ever been placed on the public record. Task Force spokesman Sergeant Al Nothum of the Missouri State Highway Patrol was quoted in contemporary reporting, as documented in Websleuths coverage from that period, noting that so far investigators had found no link between Devlin and Bianca. That finding, or rather that non-finding, was what the task force ultimately confirmed when it dissolved.
The Devlin investigation represents one of the clearest examples in this case of a lead that was pursued with significant resources, that generated significant public attention, and that produced no answer. It is a documented part of this case’s history, and it illustrates the particular difficulty of investigating the disappearance of a child when the physical record is absent from the beginning.
Our community understands what happens to hope when a lead materializes that seems, for a moment, to carry the weight of an answer and then dissolves. The discovery of Hornbeck and Ownby alive offered, briefly, the possibility that someone might be accountable for Bianca’s disappearance, too. That possibility closed in October of 2007. The family of Bianca Piper has lived through that kind of opening and closing more than once.
The years continued to accumulate around the absence of an answer. David Piper, Bianca’s father, died in 2009. He was 51 years old. The cause of death, as documented in public accounts, was a heart attack. He died four years after his youngest daughter disappeared without knowing what had happened to her.
Shannon Tanner eventually relocated from Foley to St. Charles, Missouri. According to documentation in Stories of the Unsolved, she decorated her home with photographs of Bianca and kept her daughter’s school work. She placed two electronic candles in her living room windows, a reference to the lights that Bianca had always kept hanging in her own bedroom. The family created a Facebook page, the “Bianca Noelle Piper” page, to keep the case in public awareness. These are confirmed details from the public record. They are the documented evidence of a mother maintaining a connection to a daughter she cannot find.
The 10th anniversary of Bianca’s disappearance in March of 2015 brought a St. Louis Post-Dispatch piece whose headline stated plainly what the family and investigators both knew by that point: “Family marking 10th anniversary of missing Foley girl with fading hope.” 10 years had passed. No physical evidence had been recovered. No arrest had been made. No credible named suspect had emerged from any of the investigative work conducted in that decade.
In 2018, on the 13th anniversary, KSDK in St. Louis published a piece including an interview with Tiffany Piper. Tiffany reflected publicly on what Bianca had missed across those years, the milestones of an ordinary life that her sister never got to live. She told KSDK, “Whenever she was 16 and she could have drove, being in high school and going to prom, having a boyfriend, starting her own family, holidays, just everything that we take for granted in every day of our life.” Tiffany also told KSDK that her own daughter, Abby, who would be 9 in August of 2018, used every wishbone, every dandelion, every birthday wish to wish for her aunt Bianca to come home.
In 2019, Fox 2 in St. Louis reported that Lincoln County had hired a new detective to work full-time on Bianca’s case. Shannon Tanner confirmed this development and expressed hope in her Fox 2 interview. The National Center for Missing and Exploited Children had, by that point, produced an age progression photograph, an estimated image of what Bianca might look like as an adult. Shannon told Fox 2 that she still regularly heard from people who had seen Bianca’s photo posted around town.
Our community understands what it means to keep someone alive in the world through the determined refusal to let their case be forgotten. Shannon Tanner has given interviews to St. Louis television stations, to newspapers, to anyone willing to put Bianca’s name in print or on a screen. She has done this for 20 years, not because it has produced answers, but because it is the only thing she can do.
There is a second, separate chapter of the public record connected to this family, one that sits apart from the investigation into Bianca’s disappearance. But that is part of the documented reality of what this case cost the people around it. In 2012, Bianca’s older sister Tiffany was arrested in St. Charles County, Missouri. She was charged in connection with trafficking two suburban high school girls in June of 2012. The case was prosecuted in St. Charles County. The documented details of what occurred have been reported by Fox 2 in St. Louis and other outlets.
St. Charles County Prosecutor Tim Lomar made a public statement about the case that was cited in Fox 2 coverage. He stated, “There’s a spectrum in these cases where someone can go from victim to perpetrator, and that’s what we have in this case. At some point, she was no longer a victim in this case because she perpetrated the same crimes that were perpetrated upon her.” Lomar’s statement acknowledged publicly that Tiffany had herself been a victim of human trafficking at some prior point. According to the documented prosecution record, Tiffany refused to identify who had trafficked her. That person has never been named, charged, or identified in the public record.
Tiffany Piper’s accomplice in the 2012 case, Demond Day, was sentenced in April of 2014 to 5 years in prison. Tiffany Piper was sentenced in September of 2014 to 8 years in prison. These are confirmed court records from St. Charles County, Missouri. Investigators have not publicly connected the circumstances of Tiffany’s trafficking history to Bianca’s disappearance. They are documented as separate matters. But, it is part of the public record that the older sister of a girl who disappeared at 13 in 2005 was herself identified as having been a victim of human trafficking at some point that has not been publicly specified. The person who trafficked Tiffany has never been named. These are documented facts. Their relationship to Bianca’s case, if any, has never been established on the public record.
In March of 2021, Lincoln County Sheriff Rick Harrell announced the formation of a formal cold case unit within the Lincoln County Sheriff’s Office. The Piper disappearance was explicitly identified as a priority case for the new unit. In statements to Lincoln News Now, Harrell described the purpose: fresh eyes on cases that had gone cold. He confirmed the dual status of the case—open as an investigation, cold in terms of active leads. “We still consider this an open investigation,” Harrell told Lincoln News Now. “It’s a cold case now.”
The cold case unit was modeled in part on Franklin County’s unit, which had been publicly praised by Missouri Attorney General Eric Schmitt for its effectiveness. The Lincoln County unit represented a structural commitment to cases like Bianca’s, an institutional acknowledgement that some investigations require sustained effort across years, rather than the concentrated resources of an initial response.
On February 3rd, 2023, investigators took a specific documented action in the Piper case. The Lincoln County Sheriff’s Department conducted a search of the area near where Bianca was last seen. KMOV in St. Louis reported that the search included draining a septic tank in the vicinity of the McIntosh Hill Road drop-off location. The official press release from the Sheriff’s Office described the search as part of an ongoing review of investigative files and an effort to explore all potential opportunities to uncover new evidence and develop new leads. The Sheriff’s Office did not release any findings from the search. As of the date of this production, no results from that February 2023 search have been publicly announced.
Also in 2023, the Lincoln County Sheriff’s Department confirmed a partnership with Othram, a Texas-based forensic genetic genealogy company that specializes in applying advanced DNA sequencing technology to cold cases where traditional analysis has been insufficient. Othram’s work has contributed to identifications and case resolutions in numerous cold cases across the country, including cases where evidence was decades old and previously tested material had yielded only partial profiles.
The Lincoln County partnership was reported by KMOV and is cited in the National Missing and Unidentified Persons System documentation of the Piper case. No results of Othram’s involvement in the Piper case have been publicly announced as of the date of this production.
Our community understands that forensic science in the 21st century has begun to reach into the past in ways that were not possible in 2005. DNA that was collected at a scene and placed in an evidence locker two decades ago can now sometimes yield information that it could not yield then. That is the documented hope embedded in the Othram partnership and in the resubmission of physical evidence that Chief Deputy O’Herron described in 2025. It is a specific, methodical kind of hope—not the dramatic hope of a sudden confession, but the patient hope of science doing what human memory and witness accounts could not.
In September of 2025, 20 years after Bianca Piper disappeared, the Lincoln County Sheriff’s Office announced what it described as a comprehensive new investigation into the case. Chief Deputy Wade O’Herron made statements to First Alert 4, the CBS affiliate in St. Louis, that represented the most substantive public update on the investigation in several years.
O’Herron stated, “Back in 2005, there was some physical evidence we believe that is potentially connected to the case that was tested back then. Here in the recent past, we resubmitted that evidence with the advancements in forensics to see if we could obtain any further information.”
This statement is significant in the context of everything that came before it. For 20 years, the public record of this case has not included any confirmed physical evidence connecting a specific person or location to Bianca’s disappearance. Chief Deputy O’Herron’s statement is the most specific public acknowledgement by law enforcement that physical evidence from the original investigation exists and is still being actively processed.
He did not describe the nature of that evidence. He did not say where it was collected, what it consisted of, or what the resubmission had returned. He stated only that evidence believed to be potentially connected to the case had been tested in 2005 and has since been resubmitted.
The Lincoln County Journal also covered the September announcement. That coverage included O’Herron’s full statement on what investigators have done across the years: “Our investigators have conducted an extensive amount of work on this case over the years, following up on leads, interviewing witnesses, and reviewing evidence thoroughly.”
Tiffany Piper, in the Lincoln County Journal’s coverage, confirmed that the family was grateful for the renewed investigative effort. She continued to speak publicly about her sister, about the milestones Bianca had missed, about the years that had passed, and about the family’s continued hope.
The September 2025 announcement also marked 20 years since the disappearance. 20 years in which the Lincoln County Sheriff’s Department had investigated, formed a cold case unit, searched a septic tank, partnered with a forensic genealogy company, hired a dedicated investigator, and resubmitted evidence for modern forensic analysis. 20 years in which no charge had been filed, in which no remains had been found, in which the Amber Alert had remained active.
As of January of 2026, the date confirmed by the National Center for Missing and Exploited Children’s Amber Alert Awareness Day blog post, the Amber Alert for Bianca Noelle Piper remains active. She was born on December 26th, 1991. As of this script’s production date, she would be 34 years old.
The investigation into her disappearance remains classified as open by the Lincoln County Sheriff’s Office. It is also designated a cold case, a term that describes the documented absence of actionable leads, not the indifference of the investigators who carry it. Lincoln County carries two open missing persons cases: Bianca Piper’s from 2005, and the case of 11-year-old Charles Arlin Henderson, who disappeared from Moscow Mills, Missouri, on July 25th, 1991, 14 years before Bianca disappeared.
The public record of what the investigation has confirmed is this: Bianca was dropped off on McIntosh Hill Road at approximately 6:15 in the evening on March 10th, 2005. She had no history of running away. Her family was investigated and cleared. A search of approximately 270 square miles produced no trace of her. A multi-jurisdictional task force investigating Michael Devlin found no connection to her case. A septic tank in the area was drained in 2023 with no publicly announced result. Physical evidence from 2005 has been resubmitted for modern forensic analysis with no publicly announced result. A partnership with Othram, a forensic genetic genealogy company, is in place with no publicly announced result.
The public record of what the investigation has not confirmed is equally clear: What happened on McIntosh Hill Road after Shannon Tanner drove away; whether Bianca was taken, by whom, and how; whether the physical evidence that exists is sufficient to identify a responsible person; and whether answers exist anywhere in the record that have not yet been reached.
This is not a failure of documentation. It is the honest, complete accounting of what 20 years of sustained investigative work has and has not been able to establish. The gap is real. It has existed for two decades. And an honest telling of this case requires naming it plainly.
Our community understands what Shannon Tanner meant when she told Fox 2 in 2019, “Nobody else can understand. Even your own family members can go through periods when they’re not as understanding, but only someone who has missing or lost a child can understand.”
That sentence describes an isolation specific to a particular kind of grief—the grief of a disappearance. Not a death, which can be mourned; not a confirmed outcome, which can be absorbed into the future. A disappearance is a permanent open question, the inability to grieve completely because the story has not ended.
Shannon Tanner has lived inside that question for 20 years. She moved out of the house on McIntosh Hill Road. She moved to St. Charles. She kept Bianca’s photographs and schoolwork. She kept the candles in the window. She kept talking to journalists. She kept hoping someone would see a photo posted in a town somewhere and recognize something.
There are things this case has made visible not only about Bianca Piper, but about the structures around her and the decisions that were made. The therapeutic strategy used on the night of March 10th was a documented recommendation from mental health professionals. It had been employed once before with positive results.
On the night it was employed for the second time, on a road that carried almost no traffic, in falling snow, after dark, in temperatures that were dropping below freezing, Bianca Piper walked away from the point where her mother dropped her off and was never seen again. Whether that strategy should have been used under those specific conditions is not a question that investigators or courts have publicly addressed. It is a question the family has had to carry.
The case also demonstrates the documented limits of investigative methods available in 2005. DNA testing technology in that year was capable of generating partial profiles from some forms of physical evidence. It was not capable of what forensic genetic genealogy companies like Othram can now do with that same evidence: building full genomic profiles from degraded samples, running those profiles against genealogical databases, and identifying distant relatives who might lead to a named individual.
The resubmission of evidence 20 years later is not an admission that investigators failed in 2005. It is an acknowledgement that science has changed what is possible. The existence of Othram’s involvement and the documented resubmission of physical evidence means that this case is not simply sitting on a shelf. It is being actively worked. The results of that work have not been made public. That may mean the work is ongoing. It may mean the evidence has not yet yielded the profile that genealogical research would require. The public record does not specify. What it specifies is that the work continues.
If you have information about the disappearance of Bianca Noelle Piper—anything you saw, anything you heard, anything you have held for years because you were not certain it mattered—the Lincoln County Sheriff’s Office maintains an active tip line. The phone number, as documented in the Lincoln County Journal’s September 2025 coverage, is 636-462-6513. Anonymous tips can be submitted through the Lincoln County government’s official website at lincolncomo.gov. These are verified, official channels maintained by law enforcement.
The National Center for Missing and Exploited Children maintains a database of active missing persons cases with age progression photographs for children who have been missing for extended periods. The National Missing and Unidentified Persons System, NamUs, carries Bianca’s case under case number MP4242. The Charley Project maintains a detailed, sourced, and regularly updated case file on her disappearance. These are legitimate, verified resources for anyone who wants to learn more or submit information.
Our community understands that investigations get solved by pieces of information that arrive years after the fact. By people who saw something and told no one, and who eventually decide that telling matters more than staying silent. By people who upload their own DNA to genealogical databases without knowing that a forensic match might one day be made against evidence collected on a rural Missouri road in 2005. By anyone who has held a piece of this puzzle and not yet placed it.
The documented case record also raises a question that is worth naming plainly: What does it mean when a missing child case runs 20 years without a resolution? And what are the structural realities that shape that outcome?
The Lincoln County Sheriff’s Department is a county-level agency with the staffing and resources appropriate to a county of around 44,000 people. When Bianca Piper disappeared, the immediate response was substantial. Hundreds of officers and volunteers, helicopters, search dogs, an Amber Alert. But the long-term investigation of a cold missing person’s case with no physical evidence and no named suspect is a different kind of resource challenge. It requires the sustained commitment of a dedicated investigator working across years, across dead ends, across the renewal of forensic tools as they become available.
The creation of the cold case unit in 2021 was a documented acknowledgement of that reality. It was a structural response to the fact that some cases require something other than the initial surge. The partnership with Othram represents a similar acknowledgement. The technology that Othram applies—forensic genome sequencing, genealogical research built from DNA profiles, the ability to work from degraded samples that would have yielded nothing in 2005—did not exist in usable form when Bianca disappeared. It exists now.
Whether the evidence collected in 2005 is sufficient in quality and quantity to yield the kind of profile that genealogical research requires is something the Lincoln County Sheriff’s Office has not yet publicly confirmed. The work is ongoing. The results, if they exist, have not been announced.
There are cases, documented cases, confirmed by official announcements in which forensic genealogy has reached back across decades and returned an answer. The Lady of the Dunes case, unsolved for nearly 50 years, was closed in 2023 using this technology. Cases from the 1980s and 1990s have been resolved through genealogical profiles built from evidence that sat in evidence lockers for a generation. These are facts. They are part of the reason the Lincoln County Sheriff’s Office resubmitted the Piper evidence. They are the documented basis for the hope that the resubmission might produce something that previous analysis did not.
The Piper case also sits within a documented national context. The National Missing and Unidentified Persons System, NamUs, maintains records on thousands of open missing persons cases across the United States. Cases involving children who disappeared from rural areas with no witnesses and no recovered physical remains are among the most difficult in the database to resolve. They lack the digital trail that later smartphone and surveillance technology would have provided. They lack the genealogical database depth that has accumulated in the years since commercial DNA ancestry testing became widespread. Bianca’s case is from 2005, at the edge of the period when those modern tools were not yet available, and the evidence that was collected reflects the methods of that time.
If you have ever uploaded your DNA to a public genealogical database—Ancestry, 23andMe, GEDmatch—you may have done something that, without knowing it, could eventually matter to a case like this one. When law enforcement partners with a company like Othram, the genealogical research that follows involves searching those public databases for DNA matches to a forensic profile. Distant relatives, cousins, second cousins, people who share a percentage of DNA with a person of interest become nodes in a family tree that investigators can build outward from.
The more people who are in those databases, the more effective that research can be. This is not a call to action that has anything to do with Bianca’s specific case. It is a documented fact about how forensic genealogy works, shared because it is relevant to understanding what the Lincoln County Sheriff’s Office is now pursuing.
Our community understands that the work of solving a cold case is not dramatic in the way that film and television suggest. It is methodical. It involves reviewing files that have been reviewed before. It involves resubmitting evidence and waiting for laboratory results. It involves a detective sitting with a case folder and asking, again, whether anything in it points to something that was missed. It involves hope that is measured in small increments, not in breakthroughs, but in the steady refusal to stop.
Bianca Noelle Piper was 13 years old on the evening of March 10th, 2005. She was wearing a lime green blouse and a gray Adidas hoodie. She had a flashlight. It was snowing. She was 1 mile from home. She had been in therapy since she was 4 years old. Her teachers said she was artistically talented. Her sister remembers her singing karaoke in the living room that afternoon. She loved the color purple and horses and wanted to be a singer. She would have turned 34 years old on December 26th, 2025.
The investigation is open. The Amber Alert is active. The physical evidence has been resubmitted. The tip line is staffed. The forensic genealogy work continues.
Twenty years later, no one has been charged. No remains have been found. And no one—not investigators, not courts, not the family that has carried this every day—can say with documented certainty what happened on McIntosh Hill Road after Shannon Tanner drove away.
That is the honest, complete, documented truth of this case. And it is the weight that Bianca Piper’s family has carried every single day since the night she did not come home.
