BANGOR, Maine (NEWS CENTER) -- Colin Koehler, 36, murdered Holly Boutilier in August 2009, is sentenced to life in prison.
Back in October a jury found Koehler guilty of murdering 19-year-old Boutilier under the I-395 bridge in Bangor. In May, Koehler requested a new trial, but was denied.
Assistant Attorney General Andrew Benson described the way Boutilier was murdered as a "thrill kill" for Koehler; a murder that is a slaying for pleasure. Four members of Boutilier's family spoke including her mother, Kathy Ingraham, who stated she hoped Justice William Anderson would, "put the monster who did this away for life."
Koehler's mother, Vicky Koehler, was very emotional as she spoke to Justice Anderson and acknowledged the Boutiliers loss, but described how this nightmare started for her two years ago too. She said her son was a "protector, not an aggressor."
