Ray Vannieuwenhoven killed a couple in their 20s in 1976, while they were camping. He shot the boyfriend, then chased down and raped the girl, before killing her as well.

They recently matched the DNA with the same methods used to catch the Golden State Killer, and got him to voluntarily give a sample of DNA by going to his door and pretending to take a survey, and having him lick an envelope to close it. The DNA was a match, and he was arrested. He's 82 years old.
