Seattle, Washington (CNN) - A Seattle homeless man pleaded not guilty Thursday to a decades-old murder in Maine.
63-year-old Gary Raub is charged with murdering Blanche Kimball in 19-76.
Her mutilated body was found inside her Maine home.
Police arrested Raub Monday after tricking him into giving them his D-N-A.
An undercover officer asked him to take part in a fake chewing gum survey.
They matched his D-N-A to evidence from the scene.
Raub once lived with Kimball before the murder.
He was considered a suspect back then, but there was not enough evidence to hold him.
Raub remains in jail in Washington state pending extradition back to Maine.
