Oregon 1999 Cold Case Solved – Arrest Shocked Community

For 21 years, a Portland police evidence locker held the exact genetic signature of a murderer. Not a partial profile, not a contaminated sample, a clean, single source 20 lowside DNA match sitting in storage while its owner walked free, got married to nobody’s suspicion, held down a job, and according to investigators, killed again.

 The case was never a mystery about whether there was a killer. Detectives had his blood evidence within days of the crime. What they didn’t have was his name because he’d never been arrested for anything serious enough to land in a criminal database. For two decades, that single fact was the only thing standing between Christopher Lean in a life sentence.

 Then in 2019, a private lab in Virginia did something the FBI system was never built to do. And what they found didn’t just solve a 1999 disappearance. It led police to a shed in southeast Portland and to a second victim nobody even knew was missing. This is the story of how a blood stain on a bedroom wall waited two decades for the technology to catch up to it.

 To understand why this case haunted investigators for two decades, you have to understand how unremarkable Mark Dribbon’s life was. Because that’s exactly what made his disappearance so alarming. Mark Jeffrey Dribbon was 42 years old in the summer of 1999, living alone in a single family home in the 3600 block of Northeast 137th Avenue on Portland’s east side.

 He worked as a cargo handler for United Airlines at Portland International Airport. And by every account from co-workers and supervisors, he was the employee you could set a clock by. He didn’t call in sick. He didn’t no show. He didn’t create problems. Financially stable. No criminal record, no history of risky behavior.

 Driven was in the plainest sense a man living a quiet and predictable life. He’d grown up close with his family even after distance separated them. His father Ken Dribbin and his older brother Terry both lived in Los Angeles and despite the miles between Oregon and California, Mark stayed in regular telephone contact with both of them.

 Friends and relatives who spoke about him afterward used words like gentle, reliable, unpretentious. There was nothing in his life that suggested danger was circling him. That’s precisely what makes the phone call he made on the night of July 1st, 1999 so unsettling in hindsight. Sometime that night, Dribbin called his supervisor at United Airlines.

 He asked for time off from his upcoming shift. He said he needed to deal with what he called a personal emergency. He didn’t explain further. He didn’t say who was involved or what kind of emergency it was. That call, vague, unexplained, and completely out of character for a man who never missed work, was the last confirmed communication anyone ever had with Mark Dribbin.

 He was never heard from again. For 4 days, that absence went unremarked in any official sense. But Dribbin’s reliability was so ironclad that his silence became its own alarm bell. On July 6th, after repeated failed attempts to reach him by phone, he was reported missing to the Portland Police Bureau.

 What officers found when they went to check on him would transform a missing person’s case into something far darker within hours. And it would take 21 years for anyone to learn exactly what happened inside that house. When Portland police officers arrived at Dryen’s home on Northeast 137th Avenue to conduct a welfare check, the first thing they noticed was what wasn’t there.

 Any sign of forced entry, no broken windows, no damaged door frames, no pride locks. Whoever came into that house either walked in on Driven’s own invitation or found a way in that left no physical trace. What they found inside changed everything. In the primary bedroom, officers discovered heavy blood spatter across the walls and floor, the unmistakable signature of a violent attack.

 But mixed in with that evidence of violence was something almost as telling, signs that someone had tried to clean it up. Investigators found visible white marks and traces consistent with household cleaning solutions. an attempt, clumsy but deliberate, to erase what had happened in that room. Driven himself was gone. So was his car.

 So were his house keys and personal effects. There was no body, but there didn’t need to be one. Within hours, Portland Police Bureau detectives reclassified the file from a missing person’s case to a criminal homicide investigation. The absence of forced entry led investigators down an entirely reasonable path for 1999. They theorized Dribbin likely knew his attacker, a relationship gone wrong, an acquaintance who’d been led in the door.

It was the kind of working theory that made sense given the evidence available. And it would turn out 21 years later to be completely wrong. Because despite the chemical cleanup, the killer had missed something. Swabbing of non-victim blood traces on that bedroom wall yielded an intact single source DNA profile belonging to an unknown male.

 It was clean. It was usable. It was in forensic terms exactly the kind of evidence that should crack a case wide open. 16 days later on July 18th, patrol officers found a second piece of the puzzle. Driven’s car missing since his disappearance turned up abandoned on Southeast Division Street near 43rd Avenue, parked in a neighborhood Driven had no known connection to.

 Forensic technicians processed the vehicle and pulled touch DNA from the steering wheel and door handles. When the lab compared it to the profile from the bedroom wall, it matched. Same source, same unknown man. Investigators now had two independent crime scenes, both pointing to the exact same person. A level of evidentiary consistency that should have made this an open and shut case.

 So why did it take 21 years to get a name? Here’s where the case runs into the wall that would define it for the next two decades. And it’s a wall built entirely out of how DNA databases actually work. In 1999, the standard practice was to convert biological evidence into what’s called a short tandem repeat profile or STR, a 20 loshi genetic fingerprint.

That profile gets uploaded into COTUS, the combined DNA index system, the FBI’s national database used to match crime scene evidence against known offenders. There was just one problem, and it’s a problem that sounds almost absurdly simple once you understand it. COTUS only works if the person’s DNA is already in the system.

 And a person’s DNA typically only ends up in COTUS after a felony conviction. If you’ve never been arrested and convicted of a qualifying offense, your genetic profile simply isn’t there to be matched against. No matter how many times detectives run the search, that is exactly what happened here. Detectives uploaded the profile from Driven’s bedroom wall and vehicle to Cotus in the summer of 1999.

 It returned zero matches. Not a near miss, not a partial hit, nothing. The killer’s genetic signature was sitting in an organ evidence locker. Technically identifiable, technically preserved and functionally invisible because the man who left it behind had never been convicted of anything that would put him in the database.

 With no eyewitnesses, no usable fingerprint leads, and a DNA profile that matched nothing, the investigation exhausted its options. On August 11th, 2000, the Oregon State Medical Examiner’s Office issued a presumptive death certificate for Mark Dribbin. The case went cold, but cold didn’t mean forgotten, at least not to the people who loved him.

 In May 2001, Ken Dribbin and Terry Dribbon flew from Los Angeles to Portland and stood in front of cameras at Portland Police Bureau headquarters. Ken Dribbon’s words that day captured a grief that had nowhere to go. Naturally, after this long period of time, the family would just like to have some closure, some justice.

 That closure would not come for another 19 years. The evidence sat preserved, waiting, not for a witness to come forward, not for a confession, but for the science itself to evolve into something capable of reading what the DNA had been saying all along. In March 2019, the Portland Police Bureau’s cold case homicide detail reopened the Dragon file.

 Not because a new lead had surfaced, but because the technology finally existed to use the evidence they had already had for two decades in a completely different way. Lead detective Brendan Maguire coordinated with the Oregon State Police Forensic Services Division to pull the preserved biological material from the 1999 crime scene and send it to Bod Technology, a private lab specializing in a technique called forensic genetic genealogy, FGG for short.

 To understand why this mattered, you need to understand what makes FGG fundamentally different from the CODUS process that had failed for 20 years. Traditional STR profiling looks at 20 specific genetic markers and requires an exact match to someone already logged in a criminal database. Forensic genetic genealogy does something else entirely.

 It analyzes hundreds of thousands of genetic markers across the entire genome, a technique called SNP sequencing. And instead of searching for an exact match, it searches for relatives, distant cousins, people who share fragments of DNA with the source sample, even if that source has never been arrested for anything in their life.

 Bode Technology uploaded the resulting genetic profile to public genealogy databases. Ged match and family tree DNA, the same platforms ordinary people used to research their own family trees. And the profile returned hits. Not a direct match to the killer himself, but matches to his distant relatives, third and fourth cousins who had no idea their DNA was about to help solve a murder.

 From there, genealogologists did what genealogologists do. They built the family tree upward, tracing shared ancestors, then worked their way back down through the branches generation by generation. By September 2019, that painstaking reconstruction had narrowed an entire unknown population down to something startlingly specific.

 A particular family of brothers cross referencing that small pool of candidates against residency records from Portland in July 1999 did the rest. One name matched a Portland address at the time of the murder. Christopher Charles Loverian. 20 years of silence had just ended, but not with an arrest. Not yet.

 Because there was a critical distinction detectives had to respect, one that would define exactly how this case would be built for court. It’s tempting to think that once genetic genealogy points to a name, the case is basically solved. It isn’t. and lead detective Brendan Maguire would later describe exactly why in terms that cut to the heart of how this technology actually functions inside a criminal investigation.

 They sort of point us in the direction of, hey, you may want to look at this person or this family. We still then have to target those leads and build our own evidentiary case on it. FG is an investigative lead generator. It is not by itself admissible courtroom proof. A genealogical profile built from public ancestry databases can tell police who to look at.

 But to actually charge someone with murder, investigators need a direct court admissible biological match using traditional forensic standards. That meant Christopher Lovean was now a person of interest, not yet a suspect police could arrest. On November 18th, 2019, detectives approached Lrian for a non-custodial interview. They asked him about the 1999 disappearance of Mark Dribbin.

 Love denied knowing Dribbin. He denied any involvement whatsoever. At this point, detectives had a name, a family tree, and a denial, but nothing yet that would hold up in a courtroom. What they needed was Love’s actual DNA collected directly and legally so it could be run through the same traditional STR process that had failed to identify him for 20 years this time with a specific person to test it against.

 That meant waiting, building the legal groundwork, preparing a warrant that would let them collect the one piece of evidence that could turn a genealogical lead into an arrest. And while detectives quietly built their case against a man he had no idea they were watching, Christopher Lin’s life went on, which is exactly what makes what happened just 2 months later in February 2020 so chilling in retrospect.

Because at the very moment police were closing in on a 20-year-old murder, evidence would later show Lovean was already creating a new one. On April 16th, 2020, detectives obtained a court authorized search warrant to collect a direct biological reference sample from Christopher Loverian, a buckle swab taken not from a genealogy database, but straight from the man himself.

 The Oregon State Police Forensic Services Division ran short tandem repeat testing on that sample between April 20th and April 28th. This was the same 20 lowshi STR process that had come up empty against Kotis back in 1999. Except this time, instead of searching a national database for a stranger, they were comparing Lorian’s known profile directly against the evidence recovered from Draven’s bedroom wall in his stolen vehicle two decades earlier.

 It was an exact match. 21 years after a man walked into Mark Dribbin’s bedroom, left his blood behind, and drove away in a stolen car, investigators finally had definitive court admissible proof of who he was. On April 30th, 2020, a Multma County grand jury returned an indictment against Christopher Loveran for seconddegree murder.

 4 days later at 7:46 in the morning on May 4th, 2020. US Marshall Service deputies and Portland police officers arrested Lorian in the 12,000 block of Southeast Foster Road. Portland Police Chief Jami Rash would later frame the arrest as a testament to the case’s unusual duration and the persistence it demanded. The apprehension of a murder suspect after 20 years highlights the ongoing commitment and persistence of PPB’s cold case homicide unit investigators.

 For the Draven family, this should have been the end of the story the moment two decades of unanswered questions finally resolved. Instead, it was about to become something far larger and far more disturbing than anyone in that family could have anticipated. Two days after the arrest, on May 6th, 2020, detectives executed a search warrant at Leanne’s southeast Portland residence.

 In his finished basement, they found six firearms mounted and stored, two 9mm pistols, a40 caliber pistol, a third 357 revolver, and two.223 rifles. Given Lovean’s prior felony conviction, every one of those weapons was illegal for him to possess. It was a significant discovery on its own. evidence of an armed convicted felon hiding in plain sight for years.

 But it wasn’t the discovery that would define the case’s second act that came from somewhere far less dramatic. A recorded telephone call from inside the Multma County detention center. While incarcerated and awaiting proceedings on the drive-in charge, Lovean made a series of recorded jailhouse calls to his brother. Every one of them monitored as jail calls always are.

 In one of those calls, Lian said something investigators could not ignore. There is more to this than has been revealed, and it’s bad. That single sentence spoken to a family member on a monitored line became the thread that unraveled the second murder. Detectives used it to obtain an expanded search warrant. this time targeting the outbuildings on Lrian’s property.

Structures that hadn’t been part of the original search and in a strange twist buried in the court record. It was Loveian’s own defense attorney at the time who inadvertently opened the door, inviting detectives back to the property under the belief they were simply looking for personal items connected to the driving case.

 What they found instead on May 19th, 2020, inside an exterior shed was three plastic storage totes. Inside them, the dismembered remains of a man named Kenneth Griffin. Kenneth Griffin was 53 years old, a part-time roofer, last seen alive on February 1st, 2020, reported missing the very next day. For nearly 4 months, his disappearance had existed as a separate, seemingly unrelated case with no connection drawn to the two decade old Dribbin homicide that Portland detectives had just cracked using genetic genealogy. The connection, once

investigators pieced it together, was almost unbearably simple. Griffin had met Christopher Lanne at the 82nd Street Bar and Grill after winning money gambling. Love invited him back to his home. Griffin never left. He was killed and dismembered. His remains sealed into plastic totes and left in a shed on Lovean’s own property where they sat undiscovered for months until a jailhouse phone call about an unrelated murder led detectives straight to them.

On May 21st, 2020, the Multma County Medical Examiner officially ruled Griffin’s death a homicide. And with that ruling, the true shape of the Dribbin case shifted entirely. This was never a case about a single isolated act of violence in 1999. Prosecutors would later confirm a detail that reframed everything.

 Love had no prior connection to either victim. Driven and Griffin were complete strangers to him and to each other. He wasn’t settling a grudge or resolving a personal dispute. the theory investigators had leaned on for 20 years. He was, in the language prosecutors ultimately used, a stranger predator, someone who killed people he had no relationship with at all.

Separated by 21 years, connected only by the fact that he chose them. That reframing raised an unavoidable question that spread through southeast Portland in the months that followed. If Loveian had killed two strangers two decades apart, who else might be missing? In March 2021, that question moved from public speculation to official concern.

The Multma County District Attorney’s Office issued a public appeal seeking information about missing persons who had lived in transient encampments beneath the Interstate 25 bridge in southeast Portland, a corridor of unhoused residents between the summer of 2019 and May 2020, and who may have had contact with Christopher Lrienne.

 It’s worth being precise here because the appeal itself was widely misunderstood at the time. Loverne was not himself homeless or transient. He was an employed metal fabricator living in a stable single family home in southeast Portland, the same home where Griffin’s remains were found. The appeal wasn’t asking whether Levian was living under that bridge.

 It was asking whether he had been interacting with people who did. A distinction that got lost in early public discussion, but mattered enormously to understanding who this man actually was. That appeal and the reasonable fear behind it spread across local news coverage and online forensic communities on platforms like Reddit and web sleuths.

 It also at the same time formally consolidated the legal case. On March 10th, 2021, a grand jury returned a reindictment charging Loverian with two counts of secondderee murder, one for Dribben, one for Griffin, one count of first-degree abuse of a corpse related to Griffin, and six counts of felon in possession of a firearm for the weapons found in his basement.

 Love pleaded not guilty to his arraignment. The following day, Moltma County District Attorney Mike Schmidt used the moment to speak directly to the 21 years that had passed since Driven’s murder. I want to acknowledge and thank the detectives of the Portland Police Bureau and the forensic scientists at the Oregon State Police for refusing to give up on cold case homicides.

 Time will never stand in the way of justice. The families and friends of those murdered never forget, and neither will we. But an indictment isn’t a resolution. Two families were still waiting, one that had waited two decades, and one still absorbing a loss only months old. What came next would take nearly three more years to reach a courtroom.

 The two homicide charges against Levianne didn’t resolve together. They split into two separate legal paths, each ending very differently. On January 12th, 2024, Levian and prosecutors finalized a negotiated plea agreement on the drive-in charge. Rather than face trial for seconddegree murder, Loveran pleaded guilty to the lesser charge of firstdegree manslaughter.

 Multma County Circuit Court Judge Christopher Ramro sentenced him to 20 years in state prison. It was during that plea hearing that Loveian said something that more than any piece of forensic evidence revealed the psychological weight he claimed to have carried for a quarter century. Addressing the court directly, he spoke about being haunted by what happened in that Portland bedroom for 24 years.

 His words, “I’ve got Satan in me.” It was as close as the case would ever come to a confession spoken in his own voice. Not a denial, not a defense, but something closer to an admission wrapped in his own private mythology of guilt. The Griffin case followed a completely different path. Rather than accept a plea, Lian chose to represent himself at trial, appearing prosay in Multma County Circuit Court from April 8th through April 15th, 2024.

He gave no opening statement. He called no witnesses in his own defense. He did, however, ask his standby council, attorney Keith Goody, to deliver the closing argument on his behalf, a strange halfmeasure from a man who had otherwise chosen to face the jury alone. It didn’t take long. On April 15th, 2024, after just 100 minutes of deliberation, the 12person jury returned its verdict.

 Guilty of seconddegree murder. Guilty of firstdegree abuse of a corpse. 11 days later on April 26th, 2024, Judge Romas handed down the sentence that would define the rest of Christopher Loveian’s life. Life imprisonment for Griffin’s murder with a minimum of 25 years before parole eligibility, ordered to run consecutively to the 20-year sentence already imposed for Dribbin’s killing.

Stacked together, the two sentences left with a mandatory minimum of 46 years behind bars before he could even be considered for release. Even after sentencing, Loveian didn’t stop fighting from behind bars. In February 2025, while incarcerated at the Snake River Correctional Institution, he filed a prosay civil rights lawsuit under federal law, naming the lead prosecutor to Multma County judges and lead detective Cliff Nelson as defendants.

 On April 16th, 2025, a US District Court judge dismissed the complaint outright, finding it failed to state a legally valid claim. For the Driven family, the resolution came without the one thing they’d always hoped for. Mark Dbin’s remains have never been recovered. 25 years after his disappearance, his body remains missing, even as the man responsible sits in state custody for the rest of his functional life.

 After the arrest and the court proceedings that followed, the Dribbon family requested privacy, expressing their gratitude through victim advocates for the persistence of the cold case detectives and forensic scientists who never let the file close. What this case ultimately proved goes well beyond one Portland bedroom.

 It demonstrated for the first time at this scale in Oregon that forensic genetic genealogy could crack a true stranger homicide, a case with no relationship between victim and killer. the exact scenario where traditional investigation is often powerless. And it proves something more unsettling that solving a decades old cold case doesn’t just close old wounds.

Sometimes it’s the only thing standing between an active predator and his next victim. Kenneth Griffin’s remains sat in that shed for months before a jailhouse phone call prompted by an unrelated murder charge filed 21 years too late finally brought him home to his family. Christopher Loverian is currently incarcerated in Oregon state custody with no possibility of parole for at least 46 years.

 Mark Dribban’s case took 21 years to crack because his killer’s DNA simply wasn’t in the system police were searching. He’s not the only cold case where that exact technical gap kept a killer free for decades. And in some of those cases, the breakthrough came from something even stranger than a genealogy database.

 If you want to see how investigators cracked a case where the DNA evidence pointed to an entire family before it ever pointed to a name, that story is waiting in the video right here. And it’s one of the clearest examples of how this technology is rewriting what cold case even means.
