COLD CASES: Media, Links, Videos, & Information *Links Only* *No Discussion*

    A man charged with murder in the 1987 killings of a young Canadian couple is facing trial in Washington state beginning this week, but the case won't challenge the new investigative technique authorities used to link him to the crime.

    William Earl Talbott II is one of dozens of men authorities have arrested for old, unsolved crimes in the past year using genetic genealogy. The practice involves identifying suspects by entering crime-scene DNA profiles into public databases that people have used for years to fill out their family trees.

    Privacy advocates have expressed concerns about whether it violates the rights of suspects and whether its use by law enforcement should be restricted. But Talbott's attorneys say how detectives found him is irrelevant to their defense to charges that he killed 18-year-old Tanya Van Cuylenborg and her boyfriend, 20-year-old Jay Cook.

    Instead, they argue that he's innocent, and that the discovery of his DNA — which investigators said was on her pants, vagina and rectum — doesn't make him a murderer.

    GUILTY: Bill Talbott convicted of murder after family tree unearths his decades-old secret
    This is the first time a suspect was nabbed using the combined powers of DNA and old-school genealogy.

    Bill Talbott, a 56-year-old Washington state man, has been found guilty of murdering Tanya van Cuylenborg and Jay Cook.

    A jury in Everett, Washington, returned a verdict after two days deliberating over a cold case murder from 1987.

    Tanya, 18, and Jay, 20, were Canadians on an overnight trip to Seattle to pick up furnace parts for Jay’s dad’s company.

    They were found brutally murdered, their bodies dumped in Snohomish and Skagit counties.

    This was not just a sordid murder case. This was the first time a suspect found using genetic genealogy has been put on trial.

    Genetic genealogy pointed investigators to the Golden State Killer in California – charged with 13 murders and countless rapes — which got law enforcement in Washington state considering what that could mean for cold cases here.

    Genetic genealogy involves forensic researchers uploading a DNA profile to a public database of DNA profiles, finding a relative, and then perusing that relative's family tree to identify a suspect.

    After the Golden State Killer was nabbed last year, Washington state law officials saw an opportunity. They uploaded the DNA profile of the mysterious man, dubbed “Individual A,” into a genetic database.

    Two second cousins popped up, a genetic genealogist perused his family tree, and within days, Bill Talbott of Monroe, Washington, became suspect number 1.

    A DNA test confirmed that Talbott’s semen was found in Tanya and at the scene of the crime.

    Talbott could appeal this conviction, but genetic genealogy would not be allowed to be part of this appeal, as the defense did not challenge the veracity of the method used to identify Talbott.

    Rather, the defense argued that the semen proves only that Talbott and Tanya had sex. The defense also noted that Tanya’s fluid was in the sample – evidence of arousal.

    The prosecution shot back: That was not evidence that she was turned on.

    The defense also said that Talbott had rented a room from a cop in the 1990s – no murderer would do that, she said. He had also passed a federal background check. The prosecution side-eyed both of those statements in the rebuttal, drawing chuckles from the gallery.
