Washington's Oldest Cold Case Solved With An Insane Twist | True Crime Documentary Cold Cases Solve With An Insane Twist #truecrimedocumentary #truecrimedocumentaries #truecrimestories At 11:30 PM, two young Canadians stepped off a ferry into Seattle. They were supposed to pick up heater parts for Jay’s father, spend one night in the family van, and drive home the next morning. They never returned. Six days later, 18-year-old Tanya Van Cuylenborg was found in a roadside ditch in rural Washington State. She had been raped, bound with zip ties, and shot in the back of the head. Two days after that, her boyfriend, 20-year-old Jay Cook, was found sixty miles away beneath a bridge. Beaten. Strangled. Bound with the same type of zip ties. The killer had scattered the crime scene across four counties. Their van was abandoned in Bellingham. Tanya’s wallet and keys were discarded near a bus station. Her Minolta X700 camera — the one she brought to photograph their first trip together — had vanished forever. But the killer made one mistake. He left DNA behind. Authorities had the biological evidence in 1987. They knew the killer’s genetic profile decades before they knew his name. But there was no match in any criminal database. No fingerprint hit. No suspect. No confession. For thirty-one years, the murders of Jay Cook and Tanya Van Cuylenborg remained one of the most haunting unsolved double homicides in the Pacific Northwest. Then a woman who had never heard their names uploaded her DNA to the internet to build a family tree. And everything changed. This is the story of Jay Cook and Tanya Van Cuylenborg. And this is the case that changed criminal investigation forever. ⚠️ Content Warning: This video discusses abduction, sexual assault, and the murders of two young victims.
