AUGUSTA, Maine (NEWS CENTER) - A homeless man from Seattle has entered a not guilty plea to a cold case murder in Maine.
Gary Raub, also known as Gary Wilson, appeared in Kennebec County Superior Court this morning to arraigned for the 1976 killing of Blanche Kimball.
The 70-year old Kimball was stabbed to death inside her State Street home in Augusta.
Raub was long considered the prime suspect in Kimball's murder.
He had been arrested for breaking into Kimball's neighbor's home through a basement window.
Investigators found Kimball's basement window had been broken in similar fashion. But it was piece of chewing gum that eventually led to Raub's arrest. Police offered him 5-dollars to enter a chewing gun contest. The gum was used to test for DNA which matched Raub to blood found in Kimball's home.
Raub's arrest marks the oldest cold case in Maine in which an arrest has been made.
