In 1987, 20-year-old Jay Cook and 18-year-old Tanya Van Cuylenborg were murdered on a trip from Victoria British Columbia to Seattle Washington. Police investigated the case for years but could not solve it. They had DNA evidence but no suspect to match it up to. It wasn't until 2018, with the help of forensic genealogy, that they were able to find out who left that DNA over 30 years ago.
