My name is Chelsea Rustad, and in 2013, I really like to solve puzzles. And genealogy kind of is like that. It offers you this endless stream of blanks to fill in. My name is Chelsea Rustad, and in 2013,
I began my search for my own family history. And it took me down lots of unexpected paths along the way. In 2015, I saw on Ancestry's Facebook page they were running a contest, and two winners would receive an Ancestry DNA Kit. They contacted me and said, Chelsea, you're one of the winners. Ancestry DNA Kit arrived. You just kind of spit in a tube, and seal it up, and then it was on its way. Did you have any idea just what kind of story your DNA would tell? I really didn't. I was a genealogy hobbyist, like millions of other people in the United States. I kind of accidentally fell into it. I'm CC Moore, and I'm an investigative genetic genealogist, and that means I used DNA to try to help law enforcement find violent criminals.
When the Golden State Killer Suspect was identified through investigative genetic genealogy, there were many people who said this wasn't a tool that would be used commonly in law enforcement. And I wanted to prove them wrong. And genetic genealogy has exposed a lot of secrets that people had hoped would remain secret. Yes, often times, it's someone's deepest, darkest secret. All I'm thinking is, oh, it's going to confirm my ethnic background. And maybe I'll get to connect with some cousins. I was excited. I was just really optimistic about, like, maybe it will uncover something cool. A young Canadian couple takes a road trip from Vancouver Island to Seattle in November 1987. 18-year-old Tanya Van Kylenborg and a 20-year-old boyfriend, J. Girlfriend, had just appeared during a round trip from the Kylenborg County has the first half of this puzzling case. In May of 2018,
I got a knock on the door and it was two investigators from Kylenborg County. And I was so confused. What are they investigating? The murder of 18-year-old Tanya Van Kylenborg. Her body was found in a ditch near the town of Kylenborg. The boyfriend, J. Cook, dead but shocked. His body found near Monroe a few days strangled with some kind of ligature. They let me know that they are investigating a family member of mine for murder. A double homicide from 1987. This was a person who was in my family tree. Did that name appear on any of the suspects list? No. That name had never been across my desk ever. Without genetic genealogy, would we know who killed Tanya and J? No. I know that my DNA played a big part of that. What's been a learning curve? This was all brand new. It's the web of matches.
It's putting those puzzle pieces together little by little. I have a problem that I'm relentless. And I don't give up. There may be no more dog and investigator than Stahomish County cold case detective Jim Sharp,
especially when it came to the murders of Tanya Van Kylenborg and J. Cook. It was probably the most horrendous unsolved case that we had. Tanya Van Kylenborg was an 18-year-old girl. She just graduated from high school. She was in a new relationship with J. Cook. On November 18, 1987, the young couple left British Columbia in J's parents' fan, heading for Seattle, Washington. J was going to go to Jen's co-heating in Seattle to pick up some furnace parts for his dad. They planned to sleep in the van near the store and drive back to Canada the next day. So when they didn't show up that evening, the families became concerned. We just had no idea where they might be or what might have transpired. Tanya's big brother, John, was a college
when he got a call from his worried father. John, would your sister ever just go off and not call your parents? No, I don't think that had ever happened. What the plans had changed and she was going to spend another night, she would have called my parents. After Tanya and J were reported missing, law enforcement began looking for them. Desperate for answers, John and his father joined the search in Seattle. Something was gravely wrong. I mean, the obvious things in terms of them being in hospital or something or just simply with a flat tire somewhere. All those more innocent explanations were pretty much vanishing. On November 24, six days after the couple disappeared, John's worst fears were confirmed. Tanya's body was found at the bottom of a ditch in rural Scagic County. Some 80 miles north of Seattle.
She wasn't wearing any pants or panties and her bra was pushed up over a breast. So it obviously looked like a rate murder. Tanya had been shot in the head at close range. She rolled down the hill. It was a quick execution. Later that evening, John had to identify his sister's body. Such a crushing feeling that all of a sudden you see her lying there. It's definitely horrific. But we had no idea still about where was J, where was the van, how did this happen, why did it happen? The next day, Tanya's wallet, the keys to the van, some bullets and a number of other items, turned up 16 miles away in Bellinham. They had been discarded under the porch of a local tavern, next to the Greyhound bus station.
Police located the van in a nearby parking lot, but J was still missing. The following day, J's body was found here underneath high bridge. He was about 70 miles south of where Tanya had been found. It was a horrible scene. Her 20-year-old boyfriend had been strangled, a pack of cigarette stuff down his throat. At Amika Insurance, we know it's not just what's inside your home that matters.

But you can stop them by voting yes by April 21st. Help put our elections back on a level playing field and let voters decide not politicians. Vote yes by April 21st. Paid for by Virginians for fair elections. What did most investigators think about this killer?
I mean, who does something like this? Right, that was the big question. This was a person who was a real predator and it was believed at the time that it was probably a serial killer or an ex-convict. But finding that predator would be challenging. Investigators and forensic scientists had four crime scenes scattered over three counties, but few clues. A bullet casing found on the hillside near Tanya's body matched those bullets collected at the tavern in Bellingham but a gun was never found. This surgical glove was discovered under the porch. Investigators believe the killer wore it to avoid leaving fingerprints. But he may have been careless. There was a palm print on the back of the van that they believed hopefully belonged to the suspect. Inside the van they found what would ultimately be the most important piece of evidence.
The black pants Tanya had been wearing. They found that there was semen on Tanya's pants and when they examined the seam and they learned that it couldn't be left from J. The sample matched the DNA found inside Tanya's body and would later be known as individual A. But the only evidence that connected all four crime scenes these plastic zip ties found near Tanya and J's bodies under the porch and inside the van. According to Detective Sharp, they were part of the killer's rape murder kit. This was a predator that was hunting for a victim that he wanted to rape. And maybe in his mind he decided that he was going to kill him too. There were two mild-mannered, soft-spoken kids. They weren't out to pick a fight with anyone. I mean, both families were just so devastated.
Hoping to find the killer, Tanya's family offered a $50,000 reward for information. Tips came in, but none panned out. The police to their credit were trying to chase down every sort of theory. Over the years, the theories and false leads would grow and more than 200 names would fill the case file. Some were convicted felons, and then there was Charles Sinclair. He was believed to be a serial killer across the Western United States. There was also an anonymous writer who sent threatening letters to J and Tanya's families, claiming to be the killer. Yeah, it was just unfathomable to think that somebody had done these murders but then was going to continue taunting the families with these letters. But every suspect's DNA was compared to individual A's profile and non-matched.
The goal was to try to figure out who did this semen sample belong to? Lisa Collins, a forensic scientist with the Washington State Patrol, uploaded individual A's profile to Kodas, the FBI's national offender database. As the years went by, just complete silence. It's disheartening, you just are afraid that this might be one of those cases that's never going to be solved. And then, more than 30 years after Tanya and J were killed, there's a break in the case. I was skeptical. I was hopeful, but I was skeptical. And I'm a believer now. We've had those original semen samples from the pants and then from Tanya's body. Trying to figure out who this sample may belong to.
That was the tedious and hard part. The man police believed killed Tanya van Kylenborg and J. Cook left behind a forensic calling to the police. The man police believed killed Tanya van Kylenborg and J. Cook left behind a forensic calling card, says Lisa Collins, but still managed to elude capture for years. And then in 2017, Detective Jim Sharp heard about an innovative tool developed by Parabond Nano Labs that uses DNA evidence to predict the genetic traits of an unknown suspect. It's called snapshot phenotypy. They gather all that information and they end up making a snapshot of what an individual with all those traits
might look similar to. Parabond was hired to use individual A's DNA to create this composite sketch, which gave Sharp some clues as to what the suspect could look like at the ages of 25, 45, and 65, but he still didn't have a name. Investigators in California say DNA evidence led them to one of the country's most notorious serial killers. And then in 2018, a stunning arrest in California opened new doors for law enforcement. The so-called Golden State Killer. The man responsible for numerous rapes and murders was finally apprehended after 43 years using genetic genealogy. Did a little light bulb go over your head at that moment? Oh yeah, big light bulb. The Golden State Killer's DNA have been uploaded to Jedmatch, a genetic database that allows users
of various consumer test kits to share and compare their DNA. This is fantastic. I need to get on this. Parabond agreed to upload individual A's DNA to Jedmatch and called in genetic genealogist CC Moore. She's known for her work on the PBS show, Finding Your Roots. So then what did you do? DNA. So all we have is DNA, and she's famed for skills and mapping family trees. But this was her first criminal case. I had had a lot of doubts whether this was the right thing for me to do, and I finally made the decision, okay, I'm going to do this, but a lot was writing on that case. It was a case she had been following for years and felt a personal connection to. Moore's parents were from the Pacific Northwest, and she was the same age as Tanya Van Kylenborg.
She was killed right when I was graduating in high school and going on to college, and my life was just really beginning and hers ended so tragically. And so I think it always stuck with me. On Friday, April 27, 2018, individual A's DNA file was uploaded to Jedmatch. It's compared against everyone that's participating in that database. And so what they're looking for are long segments of identical DNA between two people. Sometimes the match list will show up right away, and sometimes it takes a couple days. So I stayed up really late that Friday night. I kept checking and there was no matches. The next morning, more logged on to see if there was a list, and there was. And so we're hoping for at least a second cousin or closer at the top of that list, and we used to call that being struck by lightning. Were you struck by lightning in this case? Twice. We were struck by lightning twice.
On the list were two people who shared enough DNA with individual A to be his second cousins. And what was that feeling like? It was pretty exciting and scary. In this case, the cousin shared DNA with individual A, but not with each other, which meant they're related to him on different branches of his family tree. But to figure out who he was, more first had to find out who they were. Now, fortunately, one of the people at the top of that list had a really unique name. And what was her name? Chelsea Rustad? Remember, Chelsea Rustad had taken that ancestry DNA test, and then went a step further. You can download your raw DNA file to your computer and then upload it to Judmatch. I just had no inkling at all that there were secret relatives I didn't know about
or mysteries to uncover. Neither did the other second cousin, who more was also able to identify but has chosen to remain anonymous. And then I built the family trees of those top two matches and surprisingly quickly, I discovered how they converged. It only took me two hours to come to the identification of who I believed to be Tanya and Jay's killer. This is a person who had eluded, captured investigation for 31 years, and you were able to identify this person in two hours. That's the power of genetic genealogy. Yeah. But how sure were you? I was very sure. But isn't that scary, C.C.? Because your work might end up with this person in prison. Right. And at that moment,
I'm the only person in the world who knows that he's probably guilty of this crime other than him, of course. And so it is a super heavy burden. Monday morning, April 30th, Detective Jim Sharp got the news. We've got it narrowed down to one guy. And I'm thinking, I don't believe this. And my first thought is, who's the guy? They say if you want to go fast, go alone. But if you want to go far, go together. At Amika Insurance, we know what matters most to you. And we work even harder to protect it together.

30 plus years. Dozens of dead ends. Hundreds of false leads. And then in April 2018, C.C. Moore got on a computer and out of the billions of people on Earth identified through genetic genealogy, the one man she believed killed J. Cook and Tanya Van Kylenborg. Who was the person you identified? William Earl Talbot II. William Earl Talbot II. When Detective Jim Sharp heard the name, he ran it through the system and was surprised to learn that Talbot had no felony convictions. It was a new name that we had never heard of before. But it was sure nice when we found out that he only lived seven miles from the bridge where Jay's body was found. Sharp also learned that in 1987, Talbot, 24 at the time,
worked as a delivery driver and made stops near where Jay and Tanya were headed to pick up that furnace part and says that Talbot was fired a few months before the murders. So it makes sense that he was down in that area prowling around and probably ran into Jay and Tanya. But Sharp needed more than old work records and genetic genealogy. It's really just a tip. It's an investigative lead. To make it a rest, Sharp needed to be sure that the DNA left at the crime scene by the man they knew only as individual A, match William Talbot's. So somehow Sharp had to obtain a fresh DNA sample from Talbot himself. We were going to follow him until he dropped or threw away anything that had touched his mouth because we wanted his saliva on it as the best type of DNA source.
Investigators learned Talbot now drove a semi and they began tailing his truck. One day about a week later, they watched as Talbot stopped at a red light and opened the truck door. The light changes to green. He slams the door and drives away and there's a white paper coupling on the street. It's blowing around in the wind. So they jump out, they go over and they collect the cup and they call me. Sharp rushed the paper cup to forensic scientists Lisa Collins with the Washington State Patrol. They wanted me to test this cup and just see if I could get a DNA profile from it. Sharp left the cup at the lab to await the results. Cece Moore had already begun searching for Talbot online and quickly found his sisters and father on social media. I couldn't find hardly anything about him.
You know, no marriages. I could find very little footprint online at all. And that was a little unusual. Years earlier, someone else who knew nothing about the investigation had made a similar search. Chelsea Rustad. In 2013, long before she submitted her DNA to any websites, Chelsea Googled her grandpa's sister Blanche and found a lot of information online. Her daughter was a patty Talbot and patty had three daughters and one son and the son was William Earl Talbot the second. These were Chelsea's second cousins, the Talbots. Chelsea friended two of the sisters on Facebook, but their brother William was a mystery. This guy was just kind of a question mark off the grid. Chelsea figured William was estranged from his family but didn't give it much thought. Even after she uploaded her DNA to ancestry.com
and then Jedmatch. So she was stunned that day in 2018 when those investigators showed up on her doorstep and asked to see her research. Man, I'm just kind of like, wait, one of, you're saying one of my family members is connected to a murderer and they're saying, you know, yeah, it's from 1987 and the person of interest is William Earl Talbot. And I'm just kind of grasping the scope of this and, you know, sick and thinking about it. The investigators wanted to know her impression of William Talbot. I told them my theory that I think he's estranged. Detective Sharf got more details from Talbot's friends and family. He had a history of anger and violence when he was younger. He was a really angry kid. In audio taped interviews with Talbot sisters, Sharf learned William's troubles began when he was 11
and his father was seriously hurt in a motorcycle accident. The sisters say William began to lash out. And he beat me up, broke my telephone and I had to go to hospital. Another sister says William hurt her too. Still, she said she didn't think he was capable of murder. Yeah, I can be a bonehead, but not to the point of attacking or killing somebody now. But would the DNA on the paper cup tell a different story? That was on Detective Sharf's mind when he returned to the police lab and Lisa Collins shared the results of her testing. I said the profile from the cup matches individual A. It was just an amazing moment. Yeah. What did that feel like, Jim? I got tears in my eyes.
I'm like, I can't believe it is so emotional. And then I'm like, yeah, we got him. And so on May 17, 2018, nearly 31 years after two carefree teenagers set out on a road trip and never returned, Detective Sharf arrested William Talbot. He says John, we've got him. Sharf called Tanya's brother John right away, saying that at long last, individual A was in handcuffs. Yeah, I mean, that's when it really sent a chill down my spine. It was pretty overwhelming to think that it had all culminated in that moment right there. That's 31 years later. The next day, William Talbot was charged with Tanya's murder. Charges for Jay's murder soon followed. Jay's sisters spoke at a press conference. It's hard putting towards this feeling of relief, of joy,
of great sorrow, but this arrest brings. Jay's mom said the moment was bitter sweet. On one hand, we're close to closure, and on the other, we're still at a loss. And I don't have my only son, Jay. Detective Sharf told the group, he was grateful for breakthroughs in DNA technology. If it hadn't been for genetic genealogy, we wouldn't be standing here today. But would evidence obtained through genetic genealogy be allowed in court? Okay, let's go. More than three decades had passed
in so dark November days in 1987, when Jay and Tanya were found murdered. William Earl Talbot is now accused of killing both men. Now, with William Talbot's arrest, Tanya's brother, John Van Kylenborg, was finally able to face the man suspected of his sister's murder. And what did you think the first time you saw him? You just reviled. I mean, it's hard to control your emotions. Talbot pleaded not guilty to two counts of aggravated murder. And so in June of 2019, his trial began, in this now-ho-much county superior court. It was the first case ever to go to a jury trial where the suspect had been identified through investigative genetic genealogy. Although the Golden State Killer had been identified first, Talbot's trial would be held before his. And C.C. Moore was acutely aware of how much was writing
on the outcome. We didn't know at that point how genetic genealogy was going to be treated in court because there was no precedence. The prosecution was hoping to make it a non-issue. I was going to minimize the exposure by kind of downplaying the importance of the genetic genealogy. For a while, that was the part of the case that was perhaps most intriguing to people. Chief criminal deputy, Matthew Baldock, was the lead prosecutor on Talbot's case. He approached the defense with a proposal. They would stipulate to the jury that the DNA from individual A had come from William Talbot as an agreed-upon fact. Much to my surprise, they agreed? It was a major victory for the prosecution. The use of genetic genealogy to locate a suspect would not be contested in court. That was a huge relief. Really, it was the best possible outcome. So you admit that that is William Talbot's DNA, am I correct?
You're correct. That was a stipulation. Talbot's attorneys, John Scott and Rachel Ford, would argue that there's actually an innocent explanation for that DNA. Every indication of the DNA found from my client indicated consensual sex. Yes, they admit that Talbot had sex with Tanya, but they deny he raped or killed her or jaked up. They point out that Tanya and Jay were missing for several days before their bodies were found, implying that the couple must have encountered their killer later on. Tell me what you think then happened to Tanya and Jay. We don't know what happened. These kids were off to an adventure, whether they went to a bar, a restaurant, some sort of club to meet people I don't know. Talbot's lawyers say it's understandable that Talbot might not remember meeting Tanya or even where he was 30 years ago,
but it's significant they say that investigators were unable to link Talbot to the type of gun that killed Tanya, the pack of cigarettes, or the materials used to strangle Jay. So William Talbot's defense is basically that he had sex with Tanya and then somehow somebody else killed her. That's not William Talbot's defense. William Talbot's defense is that there is insufficient evidence to prove him guilty beyond a reasonable doubt. But prosecutors say they do have sufficient evidence. There's Talbot's DNA from Tanya's body and her pants. The fact that he lived just seven miles from where Jay's body was found, and the pomperant on the van, the police say, was a match to Talbot. Then there are the zip ties found at all four crime scenes. Baldoch says they proved the connection between Jay's murder and Tanya's and the van.
What do you believe the zip ties were used for? I believe that Mr. Talbot had Jay and Tanya in the van for some period of time after he abducted or kidnapped them. And I believe that he used the zip ties to restrain them. As part of his investigation, Detective Sharp had hoped to obtain a usable DNA profile from any of the zip ties. There had been a mixture of DNA on one of the zip ties that was found in Jay's van. And they weren't able to discern who all the profiles belonged to. But mid-trial forensic scientist Lisa Collins had decided to run that DNA mixture into a new software program to see if she could find a match. And to her surprise, she did. When I compared William Talbot's DNA profile to the mixture obtained from the zip tie that was found in the victim's van,
he was included as a possible contributor. But because her discovery came during trial, prosecutors felt it was too late to present to the jury, fearing it would delay the trial. Talbot elected not to take the stand and his lawyers were hopeful that the jury would agree there was not enough evidence to prove him guilty. In their closing arguments, the defense told the jury that police were unreasonably focused on the DNA. They never stopped to consider that perhaps the person who left the DNA was not the murderer. Attorney Ford argued that Detective Jim Sharp had tunnel vision. Is it at all possible that, yes, that was William Talbot's DNA, but he didn't kill either one of them. Is that possible? Sure. Is it reasonable? No. She was found without her pants or underwear.
So just practically speaking, is the claim that Mr. Talbot had consensual sex with her and then she got dressed and the person who ultimately killed her undresser? Baldox says the only reasonable theory is that Talbot had overpowered the couple with a plan of raping Tanya and then killed them both. He had zip ties, he had gloves, he had a firearm, he had ammunition. After a two-week-long trial, the jury began to deliberate, but they didn't come back that first day or the second.

Hey, I'm Josh Speagle, host of the podcast, Lunatic in the newsroom. If you enjoy journalism that drifts into my old panic, wild overthinking, and a guarantor,
nervous breakdown, Lunatic in the newsroom is for you. It's news like you've never heard before. The only newsroom with a panic button. You'll laugh, you'll cry, and gasp and horror as the show spirals completely out of control. It's not just news, it's emotionally unstable. Lunatic in the newsroom, listen today. On that third day of deliberations, the families of J. Cook and Tanya Van Kylenborg finally got news. There was a verdict. We the jury find the defendant, William Earl Talbot, the second guilty of the crime on her street murder as chart. Guilty, William Talbot had been found guilty of the aggravated murder of Tanya Van Kylenborg and guilty of the aggravated murder of J. Cook.
Just to hear the form of a jury, say guilty was surreal. Cece Moore wasn't in the courtroom, but she later saw video of Tanya's brother, John's reaction. It was as if I could see a physical burden left off his shoulders. He had told me how he had carried this burden for years. You know, he was the only sibling. He was her older brother. And so that was incredible to see. Chelsea Rustad had never spoken to either J or Tanya's family. But with their blessing, she decided to attend Talbot's sentence scene, where she first met John. I was really nervous. He looked a little bit nervous as well. She's effectively a family member of the murderer.
And so I think it was brave of her to take that risk. At the sentence saying, J. Cook's mother told the judge about the grief she has carried all these years. Some of us wanted to shirt our sweater and wear them. If it doesn't get a nose, it'll smell him. I still have that little sweater in my dressie drawer. The sentence was mandatory. Thank you. Of course, only possible sentence on each count is to impose a sentence of life without possibility of release. Two life terms in prison without parole. Chelsea says her sympathy is for J and Tanya's families, despite her genetic ties to Talbot. All right. His dad wasn't there. His sisters weren't there. He had a family member in the audience and I was there supporting the victims. Chelsea Rustad is proud that her DNA helped bring a killer to justice.
But there are some who have concerns about this new frontier in police work. It might be that you're not the Golden State Killer, but it also might be that you don't want law enforcement scrutinizing your entire family. Law professor Andrea Roth is head of the UC Berkeley Center for Law and Technology and says one of the problems she sees is that the DNA used for genetic genealogy can be very revealing. This is DNA testing that tells you a lot about a person's very sensitive information, their medical history, information about familial lines that the families themselves don't even know. Professor Roth does agree that in cases like this, genetic genealogy can be an effective tool for the public good, but she cautions that most states have no restrictions on its use. There's the concern that the government
could use your DNA for some reason other than a criminal investigation that it shouldn't be using it for, giving it to insurance companies or using DNA to find out who was at a protest meeting. We don't have evidence right now of the government doing that, but those are reasons that somebody might want to think about before they decide to upload their DNA. Because of this lack of legal oversight, Roth has deep reservations about sharing DNA on public genealogy websites. Would you not upload your DNA? I would not. But it may already be too late for Professor Roth or many other Americans to truly opt out. Experts estimate that today, more than 90% of white Americans can be identified using genetic genealogy. And that's because, says CC Moore, those of European descent are well-represented on websites like Jedmatch.
We have enough DNA. We can identify almost anyone of Northwest European ancestry. Even if it takes hours, dozens of hours, hundreds of hours, we'll get there. But in this case, after more than 30 years with no solid leads, Moore was able to use Chelsea Rustead's DNA to help locate a viable suspect in just two hours.
