(Scroll down for video) A man was busted for murder after 36 years when police analyzed his discarded piece of chewing gum, according to reports.
The 63-year-old homeless man was charged with the 1976 stabbing death of an elderly Maine woman. He was allegedly linked to the crime after detectives obtained his DNA through a fake chewing gum survey.
Gary Raub, 63, was arrested on Monday night in Seattle, Washington, in connection with the death of Blanche Kimball, 70, a retired dental technician, whose body was found stabbed 23 times inside her Augusta home on June 12, 1976. Authorities said the arrest solves the state's oldest unsolved murder in which an arrest was made.
Detectives were able to obtain DNA from Raub in July, after asking him to participate in a chewing gum survey. Authorities earlier this year produced a DNA profile of the blood found in the kitchen of Kimball.
"The estimated probability of selecting an unrelated individual at random from the FBI database population is 1 in 339 million," an analyst with Maine State Police Detective Abbe Chabot said.
Raub, who was known as Gary Wilson at the time, was last seen painting Kimball’s steps on Memorial Day in 1976, police said. Her body was found about two weeks later, when neighbors reported that she had not been seen for several days.
Raub, who once rented a room from Kimball, was interviewed twice after the murder, but was never charged. He was a suspect from the beginning of the investigation, court documents indicate.
