A New Way to Solve a Murder, Part 1: The Genetic Detectives

[0] From the New York Times, I'm Michael Barbaro.

[1] This is The Daily.

[2] A year after police used a genetic database to crack the case of the Golden State Killer, the same technique has been used to arrest nearly 40 other people.

[3] Now, for the first time, one of those cases is headed to trial.

[4] In part one of a two -part series, the story behind the tool that is transforming law enforcement and testing the limits of privacy.

[5] It's Thursday, June 6th.

[6] Heather, where does the story begin?

[7] So the story begins with this guy.

[8] It's Kurt Rogers.

[9] Hi, Kurt.

[10] Kurt Rogers.

[11] It's Heather.

[12] Hi, Heather.

[13] How are you?

[14] And Kurt Rogers is an entrepreneur.

[15] He spends his life in a lot of different kinds of businesses.

[16] At one point, he runs a series of candy shops with his father in Florida.

[17] Heather Murphy has been covered.

[18] delivering DNA technology for the times.

[19] For a long time, he worked in...

[20] Then start with creamy fresh Helmand's real manas.

[21] Trying to develop markets for Helmand's mayonnaise products in Asia.

[22] For one thing, we wanted to introduce mayonnaise into Japan.

[23] They were not familiar with mayonnaise, so there was trying to figure out how it would fit into their eating habits.

[24] And what ends up happening, though, is he...

[25] gets interested in genealogy, like a lot of people do as they get older.

[26] Throughout my life, I've been working on this as a hobby.

[27] And back then there's a site, and actually still is this site, Family Tree DNA.

[28] And somebody said, ah, you should join this project for people with the last name Rogers.

[29] And it helped people with the last name Rogers figure out how they were related.

[30] So he did, and he got really into it.

[31] He was so into it, actually.

[32] Well, I was asked to manage the Rogers group for one of the testing companies, Family Tree DNA.

[33] The pretty soon he became the administrator for the Rogers Project.

[34] And so what that really means is he's just trying to help his fellow Rogers connect.

[35] And he's doing a pretty good job at it, but he's getting frustrated because...

[36] They offered kind of a cookie cutter type of a website.

[37] It's all just a little bit clunky.

[38] And I wanted something more interactive.

[39] And so he asks his network of Rogers, does anybody know a guy?

[40] So I found a person who is very technical.

[41] oriented, which I am not.

[42] And yes, one of the Rogers knows a guy.

[43] And was able to talk him into making a few algorithms for me, so we have a much more interactive site.

[44] And then we're getting to around 2010, and he's hearing that people are starting to do DNA testing with sites like ancestry .com and 23 and me. These companies could test people, and then they could match the people they've tested with other people they've tested.

[45] But there was no way for them to match with people who'd been tested by other companies.

[46] The problem with these other sites is that you have to pay to join them.

[47] And then they analyze your DNA.

[48] And once they do that, you can only find relatives who also tested with and paid to join those sites.

[49] So he sees this opportunity to create a site where no matter who you tested with, no matter who you paid to join previously, you can take those files that those sites created, upload them for free.

[50] and find relatives who've tested with all kinds of companies.

[51] And they also sees this opportunity to help people find and understand not just how they're related to second cousins, but way more distant relatives.

[52] And so he asked this programmer, who's now his business partner, to make this.

[53] And he did it.

[54] Anyone who had been tested by any company could put their information on our site if they wish to do so.

[55] And then find matches with people who had been tested with other companies.

[56] And it was such a great program.

[57] I said, this is really too good for just my little Roger surname group.

[58] Let's start another website and share this with other people.

[59] And so that's how their website began.

[60] And how do I say Jedmatch?

[61] You said it absolutely correctly.

[62] It is Jedmatch.

[63] Kurt calls it Jedmatch.

[64] His partner calls it Gedmatch.

[65] So for people who are looking for relatives, it's a free place where they can go to find many more potential matches, no matter who the people on that site tested with.

[66] Yeah, exactly.

[67] And GetMatch just takes off.

[68] Kurt told me that he was expecting, okay, maybe 10 % growth, that would be good based on working at something like the mayonnaise business, but he is far exceeding that.

[69] The number of uploads are doubling every year, and that's without any kind of advertising.

[70] Wow.

[71] And they're growing and growing and growing so fast that at some point they crashed the server.

[72] Basically, too many people are using it.

[73] Too many people are using it.

[74] They're getting so many emails, is that Kurt's wife is really angry with him because all he's doing is responding to emails all day.

[75] One of them, let me just say, the first one I ever did that was meaningful was a woman who didn't know her father because her mother had done a test tube baby.

[76] And so she finally found her father and she got up the courage and called him and she said who she was.

[77] There was a big hesitation on the other side.

[78] And the father then said, This is the happiest day of my life.

[79] Today is my birthday, and there is no greater gift than this one.

[80] And he was crying.

[81] You know, things like that make you realize how much you do help people.

[82] That's really what it's all about, helping people.

[83] But aside from these letters, Kurt, really had no idea how people were using his site across the country.

[84] How were people using his site across the country?

[85] Well, fast forward to 2015.

[86] There's an investigator named Deputy Pete Hedley.

[87] Headley here, can I help you.

[88] And he's working on a case.

[89] Hi, can you hear me?

[90] Yes, I can.

[91] About a woman named Lisa.

[92] It begins when this woman is just five years old.

[93] This is the late 80s.

[94] She's living in a trailer park in California with her father, and he's not taking very good care of her.

[95] There was a couple there, older couple, that befriended them.

[96] And the neighbors start to notice.

[97] They knew something.

[98] was wrong.

[99] You know, living in the back of a camper shell like that, they heard Lisa crying at night sometimes.

[100] And they're talking to him and they say, oh, she's such a sweet girl.

[101] You know, we're happy to help out with her sometimes.

[102] They told him that their daughter was having a hard time having kids and she'd like to adopt.

[103] And so they take her.

[104] For what starts as a few weeks, it's this sort of trial adoption.

[105] Obviously, this is a pretty unconventional situation.

[106] And during the course of those few weeks, they start to notice that it's even worse than they thought.

[107] She's clearly been sexually abused.

[108] And during this time, he disappears.

[109] They don't know where he went.

[110] So they go to the local sheriff's department and say, what should we do?

[111] And the sheriff puts out a warrant for his arrest, both for child abandonment and for abuse.

[112] The little girl ends up in foster care.

[113] And eventually they find him and arrest him.

[114] He was in jail for about a year and a half when he was released.

[115] He immediately absconded parole and his location was unknown again until...

[116] And then quite a few years later, he was arrested in 2002 in Contra Costa County.

[117] He's arrested again, this time, for murder.

[118] And when they arrested him, they ran his fingerprints, and it came back with all these other AKAs.

[119] So you had a list of different identities, like how many identities?

[120] were talking for him.

[121] Let me see.

[122] We have Robert Evans, Curtis Kimball, Gordon Curtis Jensen, Harold Mockerman, Lawrence Vanner, Hulus Jensen, and different variations on the names.

[123] And they saw his previous criminal history involving Lisa, and they obtained DNA from him at that time and compared it to Lisa.

[124] And at that point, everyone realized he's not related at all.

[125] Where did he get this kid?

[126] That's when we went back and reopened the case to try to determine who she really was and where he took her from.

[127] So that little girl whose neighbors were concerned about her dad and that that got arrested and she goes into foster care, this test is showing he's not actually her dad.

[128] That's right.

[129] So this woman grew up thinking.

[130] that she was abandoned by her abusive father.

[131] Now as an adult, she's learning.

[132] Actually, her abusive father was not her father.

[133] He was her kidnapper.

[134] Well, we know the suspect kidnapped her.

[135] And she has no idea who she is.

[136] But we don't know who she is.

[137] So we're trying to determine who she is.

[138] So Deputy Pete Hedley, he's one of these traditional cold case detectives who never give up.

[139] I just kept hitting dead ends, and it was really frustrating.

[140] But, you know, I had promised Lisa that I wouldn't give up.

[141] They just keep working and working and working and working a case.

[142] And so I just kept trying to think of any possible way that we could identify her.

[143] We'll be right back.

[144] So Detective Pete Hedley is hitting dead end after dead end in the Lisa case.

[145] What does he do?

[146] So by 2015, he started to start.

[147] to hear that adoptees are finding their biological parents through these genealogy sites.

[148] And he thinks, wait, actually, couldn't that help us?

[149] So he reaches out to an organization that's known for this type of thing.

[150] I just sent an email to DNAadoption .com asking them if the same methods that they use to find adoptees' biofamilies could be used to identify Lisa.

[151] Barbara Ray Venture responded to my email.

[152] Okay, I'm going to take the headphones off.

[153] one second.

[154] I need to take my earrings off.

[155] And who is Barbara Ray Venter?

[156] Barbara Ray Venter is a very interesting character.

[157] I arrived in the U .S. in December 68.

[158] She's originally from New Zealand.

[159] I applied to the University of Texas Law School, and I was accepted.

[160] She spent a lot of her life as a patent attorney, and she worked on all kinds of interesting biotech innovations.

[161] Anything from new organisms for making better strains of penicillin, including the first genetically modified.

[162] fruit to the flavor saver tomato.

[163] The flavor saver tomato for a company that later became part of Monsanto.

[164] Did you ever find yourself having to defend your employer to your friends?

[165] I didn't make a big point of mentioning that I did genetically modified food and other things.

[166] No. As she got older in life, she got interested in genealogy as many people do, and she volunteered with an organization called DNA adoption, where she helped adoptees to find their biological parents, and she was really good at it.

[167] For me, of course, I understand all the science.

[168] I don't need tutorials on that.

[169] So for me, it was probably a little easier than for most people, because all I'm trying to learn is how to actually use the DNA in conjunction with research techniques for traditional family history research.

[170] And then one day, she gets a message from Deputy P. Headley.

[171] I was working on my computer on something, and the email came in, and to me, it was an intriguing question.

[172] could we, in fact, identify somebody who had no clue who she was when all we really would have is her DNA.

[173] We didn't know anything else about her.

[174] That's when Barbara Reventer responded back and said, yes.

[175] But because we had no geographic information on her, it was going to be difficult.

[176] So how does she go about finding this woman's parents?

[177] I mainly worked through Deputy Headley, but I did have conversations with Lisa at various times.

[178] She's a very charming, very sweet person, but she also is obviously wanting to very much maintain her privacy.

[179] So what she needs to do is she needs to find some relatives, hopefully close relatives.

[180] Theoretically, the technique that we were using for finding both relatives should work for somebody like Lisa.

[181] And so I had Lisa test at Ancestry 23NMe and family tree DNA.

[182] And also upload to Jedmatch.

[183] Kurt's site, Gemmatch, is an essential tool for her.

[184] And all the matches that showed up there, Barbara would build a tree up from these people that are related to her until the trees cross and you get to an ancestor in common.

[185] I hope that it's somebody relatively close like a great -grandparent or a great -great -grandparent.

[186] And at that point, I then search for all of the descendants of that common ancestor.

[187] So then she can say, your victim is a descendant of this ancestor in common.

[188] And then as she followed the trees back down to the living folk, I would use all of our law enforcement resources to find those living people and contact them.

[189] Like what kind of resources?

[190] Everything from DMV records to old census records.

[191] But at this point, my primary job with Barbara was to find the living folk and call them up and start asking them to do a DNA test.

[192] and that's how you narrow it again, is the amount of matching DNA increases, you know that you're getting closer to the correct family descendants.

[193] And what did you say when you contacted them?

[194] It was difficult, making cold calls like that.

[195] I would always start off with, I'm working on a cold case, and I'm hoping you can help me out.

[196] Some people, they would just hang up.

[197] A lot of people thought it was a scam.

[198] I had one woman that thought I was going to try to clone her.

[199] Yeah.

[200] So this goes on for many months.

[201] Barbara estimates at the end that it takes 20 ,000 hours of work from about 100 volunteers, many of whom are distant relations of Lisa's.

[202] The maternal line tree in particular was enormous.

[203] It had something like 18 ,000 people in it.

[204] So eventually, they narrow Lisa's father down to one of five brothers who seemed to live in New Hampshire.

[205] Unfortunately, all of the brothers were married when Lisa was conceived, and so they're not really happy to hear that they might have this other child.

[206] Got it.

[207] Yeah.

[208] So they don't want to be tested, which is not helpful.

[209] On the other side of Lisa's family, though, on her mother's side, Barbara and her team have more luck.

[210] They eventually find this person who, based on looking at the family tree, appears likely to be Lisa's grandfather.

[211] That's a breakthrough.

[212] It's a breakthrough.

[213] He is also skeptical of all of this at first, but they eventually convince him it's legit and he agrees to be helpful, partly because another family member convinces him.

[214] And they do a DNA test.

[215] And what they find is it confirms that he is indeed Lisa's grandfather.

[216] And what her grandfather tells her is the last time he saw her, she was two.

[217] And her mother was involved with this guy.

[218] And his name was Bob Evans.

[219] Family didn't know a lot about him.

[220] At the time, he talked up that they owed money to a bunch of people, insinuated that it was to dangerous, bad people that they owed money to even.

[221] But in the middle of the night, they absconded, and the family never heard from them again.

[222] And they just assumed that she'd just gone off with this guy.

[223] They didn't know what had happened.

[224] That's when I contacted Manchester Police Department.

[225] and briefed them on the case, told him this is a missing person.

[226] Denise Bowden moved away with this guy, Bob Evans, and she's actually a missing person.

[227] So what did you tell Lisa?

[228] When I called her up, I told her that we had been able to figure it out.

[229] And she got very quiet.

[230] And then I asked her if she'd like to know her name.

[231] So what happened?

[232] I told her her name is Don Bowden and then she called me a couple days later had some time to think about it and was wondering well should she change her day to birth, change her name?

[233] It had to be a big shock and I just told her that's something for you to think about and decide on It was very emotional being able to actually do that for her particularly knowing what had happened to her and so it was very nice to be able to give her back her family and to give her her name.

[234] It was very satisfying to be able to tell her who she is.

[235] It made it all worth it.

[236] So what Deputy Pete Headley and other investigators believe is that sometime after he kidnapped Don, he killed her mom.

[237] They have not found her body, but the reason they believe this is because this was part of a pattern of behavior.

[238] It's believed that he killed at least two other women he was involved with and three children.

[239] Wow, but not Don.

[240] But not Don.

[241] We still do not know the extent of his crimes, but he's known as the Bear Brook killer, and he died in prison.

[242] So I just want to get this straight.

[243] that little girl who is taken by her neighbors and ends up in the hands of police the man who she thought was her father was actually a serial killer who kidnapped and likely murdered her mother.

[244] Yes.

[245] And Lisa is Dawn.

[246] Lisa is Dawn.

[247] And Barbara has done all this using GEDmatch.

[248] Yes.

[249] And this is a really big deal because it shows that you can use GEDmatch and use family tree building techniques to identify much more than just an adoptees' parents.

[250] You can identify a person.

[251] And so word gets out that Barbara and Pete solved the Lisa case.

[252] And eventually there's another investigator.

[253] He's been working on this cold case for decades.

[254] He has no real leads.

[255] All he has is some crime scene DNA.

[256] And so he reaches out and asks for help.

[257] Police finally got their break in the Golden State Killer case by combing through commercial genealogy website.

[258] And this is the case of the Golden State Killer.

[259] Police say one of the most elusive serial killers in American history.

[260] Golden State Killer.

[261] The Golden State Killer.

[262] The Golden State Killer has been captured at least 12 murders.

[263] Forty -five rapes and more than 100 burglaries.

[264] They have been searching for more than four decades, and tonight the major clue.

[265] Investigators compare DNA found at the crime scene.

[266] We found the needle in the haystack.

[267] genetic information listed on the websites, which...

[268] He's been called the East Side Rapists, the Bicelia Ransacker, the original Nightstocker, and the Golden State Killer.

[269] Today, it's our pleasure to call him defendant.

[270] So all of this work from the Lisa case has led to this groundbreaking moment.

[271] This is the first time that we're seeing a public arrest in such a high -profile case, the case of a serial killer that has eluded detectives for decades.

[272] And now they finally have a name.

[273] They finally have somebody behind bars.

[274] And that is because they have used this technique that people are calling genetic genealogy.

[275] And that leads us back to the site that Kurt Rogers built, GEDmatch.

[276] Yeah.

[277] It's only after the announcement that the alleged Golden State Killer has been arrested, Kurt told me that he learned that his site had been pivotal to this investigation.

[278] He had been asked previously if his site could be used by law enforcement to identify murderers and rapists and he'd actually said no, he couldn't explicitly sanction it because people who were there primarily for genealogical research no one was expecting to be cooperating with law enforcement.

[279] My concerns were that there could be a violation of privacy.

[280] I had to figure that out my head if that was true or not.

[281] And what helped you figure it out?

[282] time, a lot of sleepless nights.

[283] But then he starts getting these emails, and they are so congratulatory.

[284] They are telling him that he has done great things for the world, and he is feeling incredibly proud of what he has created.

[285] It's like when they first discovered that fingerprints could be used to identify individuals.

[286] We've now started a whole new field of forensics.

[287] It's not as direct as fingerprints.

[288] Don't get me wrong, but it's a whole new way of finding people.

[289] So he and his partner decide to officially open up, get matched to law enforcement.

[290] To me, the real important thing was the people who've been victims, and that includes their families.

[291] And bringing closure to them is extremely important to me. It really is.

[292] And they rewrite the user agreement.

[293] so that what it now says is that by default, users are opted in to allow their profiles to be searched by law enforcement for the purposes of sexual assault and murder cases.

[294] I'd never realized how many families and people there are out there who have been suffering for decades because of some violent crime that's happened in their family.

[295] And there must be millions, literally millions of people like that.

[296] And that changed ever.

[297] everything.

[298] Tomorrow on the Daily, part two of the story.

[299] At the time of the Golden State Killer suspect arrest, a lot of people were opining that this was going to be a one -off, that it was too difficult, too much time investment, et cetera.

[300] And I wanted to prove that that wasn't true, that the power of genetic genealogy could absolutely be applied to cold cases and even active cases.

[301] There was no reason that that couldn't happen.

[302] We'll be right back.

[303] Here's what else you need to know today.

[304] On Wednesday, YouTube said it would remove thousands of videos and channels that advocate for bigoted ideologies like neo -Nazism and white supremacy in the latest attempt by a major technology company to limit hate speech.

[305] YouTube, which is owned by Google, said its new policy would ban videos that justify discrimination by claiming a specific group is superior to others or that deny the existence of violent incidents, such as the Holocaust and the Sandy Hook school shooting.

[306] And the Trump administration said it would drastically reduce federal spending on medical research that uses tissue from aborted fetuses, fulfilling a long -time goal of anti -abortion groups.

[307] Scientists have long used fetal tissue to test drugs and vaccines, targeting everything from HIV to cancer, and say that in many cases there is no substitute.

[308] But opponents, including Representative Steve Scalise, the number two Republican in the House of Representatives, called federal funding of such research.

[309] Immoral.

[310] That's it for the daily.

[311] I'm Michael Wobarro.

[312] See you tomorrow.
