Episode 268: On November 18, 1987, Jay Cook, 20, and Tanya Van Cuylenborg, 18, a young couple from Vancouver Island, went on a road trip to Seattle, Washington. Unfortunately, they were never seen alive again.

Their bodies were discovered weeks later in separate locations. Tanya had been raped, shot, and left in a ditch in Skagit County. Jay was found strangled in the woods near Monroe, about 60 miles away.

The case went unsolved for over three decades until 2018, when authorities were able to use genetic genealogy to identify a suspect. He was arrested and charged with the murders. The man pleaded not guilty. In 2021, after his trial, the man was the first to be convicted using genetic genealogy. The couple’s killer was subsequently sentenced to life behind bars.
