(Newser) – A Seattle man accused of a horrific murder in Maine 36 years ago was busted after an undercover cop got his DNA by persuading him to take part in a "chewing gum survey," the Daily Mail reports. The DNA obtained from 63-year-old transient Gary Raub matched that of blood found at the scene of the murder of his former landlady in 1976. She had been stabbed dozens of times. Police interviewed Raub twice after the murder, but he denied involvement. This is the oldest cold case killing in Maine in which an arrest has been made.
