Tennessee 1991 Cold Case Solved – Arrest Accidentally Revealed Serial Killer

March 10th, 1991, Spring Hill, Tennessee. A man walking near Saturn Parkway stops cold. Just off the wood line, 100 ft from the Port Royal Road off-ramp, lies the body of a woman. Her clothes are torn. Her neck bears the unmistakable marks of a struggle for life that she lost. She has no name, no ID, no one waiting for her, as far as anyone in Spring Hill knows.

 What the medical examiner discovers next changes everything. This woman was 24 weeks pregnant. Her unborn daughter died with her. For nearly a month, she is simply a Jane Doe in a Tennessee morg. And the man who left her there is already gone. Driving an 18-wheeler down another highway in another state, becoming someone else’s problem before Tennessee even knows her name.

 It would take 34 years, three states, two more bodies, and a piece of panty hose kept frozen in an evidence locker to finally catch him. This is the story of how a mobile killer stayed invisible for three decades and the science that finally found him. Before she was a case file, she was a person.

 Pamela Rose Aldridge McCall, friends called her Rose, grew up in topping, a small coastal town in Middle Sex County, Virginia. She was 33 years old, though for years afterwards, secondary reports would get her age and even the length of her pregnancy wrong. It’s the primary charging documents and the Tennessee Medical Examiner’s own records that settle it.

 33 years old, 24 weeks pregnant. Rose lived a life that was hard to pin down. She moved constantly between Virginia and Tennessee, and she did it the way a lot of people without steady means did back then. She hitchhiked. She had a son and a brother back home. People who loved her and who would spend decades not knowing what happened to her.

 In early March of 1991, witnesses place her at the Union 76 truck stop off Interstate 65 in Middle Tennessee. She’s seen getting into a semitr riding with an unidentified male driver. It’s an ordinary moment, the kind that happened a thousand times a day on America’s interstates. Except this time, it was the last time anyone would ever see her alive.

 That single detail, a woman getting into a truck cab with a stranger, is about to become the thread that connects three murders across three states. But in March of 1991, nobody in Spring Hill, Tennessee, has any idea a pattern even exists. All they have is a body and no name to put on it. When investigators reached the wood line off Saturn Parkway, the evidence told a brutal fast story.

 Rose’s clothing, including her undergarments, had been torn from her body. Her face and neck showed severe trauma. The autopsy would later confirm what the scene already suggested, manual strangulation, homicide, because of where the body was found, right beside the westbound off-ramp for Port Royal Road. Detectives formed a working theory.

 They believed she’d been attacked inside a truck cab and that her body had then been rolled down the embankment near the ramp. It was a theory, not a confirmed fact, but it fit everything else they knew. The truck stopped citing the trucker companion, the location. Then came a decision that nobody in that moment could have known was the most important one of the entire 34-year case.

Technicians recovered Rose’s panty hose. On it, they found traces of siminal fluid. In 1991, there was no real way to use that evidence. The DNA technology to analyze a sample that small simply didn’t exist yet. But instead of discarding it, someone made the call to freeze it and preserve it. That single piece of fabric sealed away in a police evidence freezer would end up outliving witnesses, outliving careers, and outliving the killer’s ability to hide.

But that payoff was 30 years away. In 1991, all Ron Coleman and his team had was a strangled woman, a truck stop lead that led nowhere, and a killer who was already three states down the highway. Officer Ron Coleman caught the case, and almost immediately he hit a wall that had nothing to do with effort.

 For nearly a month, the victim herself was unidentified. She lay in the morg as a Jane Doe until April 9th, 1991 when a fingerprint match finally gave investigators a name. Pamela Rose Aldridge McCall with a name. Coleman could trace her movements. The hitchhiking route between Virginia and Tennessee, the sighting at the Union 76 truck stop, the unidentified trucker.

 He interviewed truck stop employees. He interviewed transients who passed through the area. He interviewed drivers who ran that stretch of I65 regularly and then nothing, no vehicle description, no license plate, no local suspect who fit. The killer wasn’t from Spring Hill. He had no ties to the town, no reason to come back, and by the time McCall’s body was even identified, he was long gone, invisible to a small town police department.

 With no way to search beyond its own jurisdiction, Coleman made a personal promise to Rose’s mother that he would not stop until her daughter’s killer was found. It’s the kind of promise investigators make when they still believe the case is solvable in months, not decades. But the months became years. The leads that existed dried up completely.

 And in 2002, Coleman retired as assistant chief of the Spring Hill Police Department. With that promise still unfulfilled, the case was officially cold. But while Spring Hill’s investigation stalled, something else was already happening a thousand miles away. Something nobody in Tennessee could have connected yet. Because the man who killed Pamela McCall wasn’t finished to understand why this case took so long to break.

 You have to understand what was happening on other highways in other states. All while Tennessee investigators worked in isolation. Just weeks before McCall’s murder. In February of 1991, a 21-year-old hitchhiker named Mary Anne Newton was picked up in Wheeler County, Texas. She was bound, raped, and choked inside the sleeper cab of a commercial truck.

 Newton fought back and managed to escape at a gas station. Her attacker was arrested, but the case fell apart when her trauma made it impossible for her to return to Texas and testify. He walked free. Then in the fall of 1991 into early 1992, an unidentified woman, later nicknamed Bitter Creek Betty, was assaulted and strangled in Sweetwater County, Wyoming.

 Her body was found frozen and nude along Interstate 80 in March of 1992. Just weeks after that, in April of 1992, Wyoming Highway Patrolman discovered another body, a mummified pregnant woman in a ditch along Interstate 90 in Sheridan County. She became known only as I Jane Doe. Three women, three states, all connected by highways, all encountered by a driver moving cargo across state lines.

 And not one police department had any reason to believe these cases were related. Wheeler County worked its case. Spring Hill worked its case. Sweetwater County and Sheridan County each worked theirs. There was no shared database, no phone call linking Texas to Tennessee to Wyoming. Each agency was staring at one piece of a puzzle none of them knew existed.

 It would take 21 years just for two of those pieces to connect. And even then, it would be a match between bodies, not a name. In 2012, the Wyoming State Crime Lab ran DNA profiles recovered from the Bitter Creek Betty and I90 Jane Doe crime scenes against each other. They matched. Same unknown male offender. For the first time, someone had proof this wasn’t two isolated murders.

 It was one man killing along two different interstates. But a match between two unidentified crime scenes still isn’t a name. Wyoming now knew they were hunting a single serial killer. They still had no idea who he was. And they had no idea he’d already killed in Tennessee, too. That connection, the one that would blow this case wide open, wouldn’t come from new violence.

 It would come from an old piece of evidence that had been sitting in a freezer since 1991, waiting for the technology to finally catch up to it. In April of 2019, the Spring Hill Police Department made a call to the 22nd Judicial District Attorney’s Office requesting help reopening the McCall case. Since 2014, that office had run a dedicated cold case initiative that had already cracked several old homicides.

Investigator Tommy Gets took the lead. Gets first move, but crucial. Find the physical evidence from 1991. He tracked down the frozen panty hose and submitted it to the Tennessee Bureau of Investigations forensic chemistry and DNA unit using modern short tandem repeat or STR amplification technology that didn’t exist when Rose died.

 TBI scientists pulled a clean full DNA profile of an unknown white male from that decade’s old sample. They ran it through COTUS, the national DNA database, and they got a hit. The DNA from Rose McCall’s pantyhose matched a profile Wyoming investigators had developed years earlier. The same profile connecting Bitter Creek Betty and I90 Jane Doe.

 In an instant, a cold Tennessee homicide from 1991 was revealed to be part of a multi-state serial killer trail spanning at least three victims in two states. But Cotis could only tell them the same man did all three murders. It couldn’t tell them his name. For that, investigators would need to go further than any database. into the killer’s own family tree.

 With the FBI now coordinating, Tommy Gets and Wyoming’s Division of Criminal Investigation brought in a private lab to run investigative genetic genealogy, IGG, instead of searching a database of criminal offenders. IGG maps hundreds of thousands of genetic markers and searches public genealogy sites where ordinary people upload their own DNA to learn about their ancestry.

 Somewhere in that public data, without knowing it, the killer’s own relatives had left a trail back to him. The genealogologist built out a family tree branch by branch, narrowing an entire population down to one plausible name. Clark Perry Baldwin, born August 22nd, 1961 in Charles City, Iowa. Raised in Nshua, Iowa, graduated high school in 1979 and went almost immediately into a career as a longhaul commercial truck driver for Martin Transport, a job that put him on exactly the highway corridors where three women had died. Investigators now

had a name. What they needed next was proof solid enough to survive a courtroom. And to get it, they wouldn’t ask Baldwin for a DNA sample. They’d have to take one without him ever knowing. In April of 2020, FBI surveillance teams began quietly watching Clark Perry Baldwin in Waterl, Iowa. They didn’t approach him.

 They didn’t tip him off. They waited for him to leave something behind. At a local Walmart, agents watched Baldwin use a shopping cart. And after he walked away, they retrieved the handle. They also collected trash from his household waste. Both samples went to the Wyoming State Crime Lab for STR analysis. The result, a perfect match to the DNA recovered from Pamela McCall’s panty hose and to the DNA from both Wyoming crime scenes. Three murders, one man.

Nearly 30 years of running. On May 6th, 2020, investigators Tommy Gets and Ly Young knocked on the door of Baldwin’s sixth floor apartment. It took him 4 minutes to answer. When he did, he let them in into a room with nothing but a single couch. Over the next hour, wearing concealed recording devices, they spoke with him.

 He denied remembering McCall by name, but admitted he may have had sex with her, adding that she was a prostitute. He showed no visible emotion. Only after that recorded conversation did get read him his Miranda rights. Clark Perry Baldwin was arrested on firstdegree murder warrants from both Tennessee and Wyoming.

 34 years after Pamela McCall was left in the woods off Saturn Parkway, her killer finally had a name attached to handcuffs. But an arrest isn’t a conviction, and getting Baldwin in front of a jury would take five more years. The case landed in Mari County, Tennessee, where Baldwin was indicted on two counts of firstdegree murder, one for Pamela McCall, and a second under Tennessee’s fetal homicide statute for her unborn daughter.

 District Attorney General Brent Cooper led the prosecution. Getting to trial took until 2025. 5 years of pre-trial motions challenging the legality of that Walmart cart and household trash DNA, pandemic related court shutdowns, and the sheer logistics of moving decades old evidence between three states. When the trial finally began in April 2025, prosecutors leaned on two pillars.

 DNA evidence that TBI analysts testified was for all practical purposes conclusive and the testimony of a woman who had survived him. Maryanne Newton, the same hitchhiker Baldwin had attacked in Texas back in February 1991, took the stand. She described being bound, gagged, and choked nearly to death in his truck and recounted a moment that silenced the courtroom.

 Baldwin handing her a gun and telling her, “If I were you, I would shoot me.” The defense pushed back, arguing McCall’s contact with Baldwin was a consensual paid encounter and that the state couldn’t prove he was the one who strangled her, suggesting someone else could have done it after he left. The jury didn’t buy it. On May 2nd, 2025, Clark Perry Baldwin was found guilty on both counts of first-degree murder and sentenced to life without parole. It should have been the end.

 It wasn’t, not quite. Baldwin still owed Wyoming an answer for two more murders. In the week following his conviction, Wyoming’s Division of Criminal Investigation publicly named the I90 Jane Doe victim. Cindy Arlene Estrada, identified on July 17th, 2025. Bitter Creek Betty had already been quietly identified back in 2022 as Irene Vasquez.

 Though that information had been kept sealed, Baldwin was set to be extradited to Wyoming to finally face charges for both of their deaths. He never made it. On July 18th, 2025, one single day after Estrada’s name was made public. Clark Perry Baldwin died of a heart attack in the Mory County Jail. The Wyoming cases would never see a courtroom.

 The full truth of his final hours with Irene Basquez and Cindy Arlene Estrada died with him. For McCll’s family, the ending was bittersweet in the truest sense. Her mother had lived to see her daughter’s killer identified and arrested in 2020. She once told District Attorney General Brent Cooper, “At least I have a grave to visit.

 Some moms don’t even have that.” But she passed away before the 2025 trial, never hearing the guilty verdict read aloud. Rose’s brother and son were there in her place. And after the verdict, they thanked the Spring Hill Police Department and the Mory County community for never letting the case die. Strip away the decades and the states and the courtroom drama.

 In this case comes down to one decision made in 1991. Someone chose to freeze a piece of evidence they had no way to use yet just in case science ever caught up. It took nearly 30 years, but it did. This case also exposed something uncomfortable that a man with no felony DNA record, no COTUS profile, and no ties to any of the towns where he killed could drive right past justice for three decades simply by staying in motion.

 It wasn’t until investigators stopped searching criminal databases and started searching ordinary family trees, the same public genealogy sites millions of people use for curiosity, not justice, that his own relatives unknowingly led police straight to him. Wyoming never got its day in court with Clark Perry Baldwin. Irene Vasquez and Cindy Arlene Estrada are still in a legal sense waiting for justice that will now never come in a courtroom.

 And there’s still one named true crime forums keep bringing up in connection with Baldwin. Tammy Joseiki, the Illinois college student who vanished off Interstate 80 in 1992. Investigators looked hard at Baldwin for that one, too. What they found and why they ultimately ruled him out is a story on its own.

 If you want to know how that investigation played out, and why some cold cases stay cold even after the killer is finally caught, that’s the video to watch next.
