A police affidavit released this week gives more details into the night Corporal Eugene Cole was shot and killed, including a possible motive.

According to the Portland Press Herald, the report states that Cole approached suspect John Williams in the early morning hours of April 25th as he was trying to get into the home of Kim Sirois. Williams had lived at the home for a while, until Sirois asked him to leave because of his drug use. The suspect later told police he didn't know why Cole was trying to arrest him on that night. He struggled with Cole and pulled away from him. Cole stepped backward, tripped, and fell to the ground. At this point, Williams says he pulled a handgun from his waistband, took off the safety, and shot Cole in the head.

Williams later told police that he was upset that Cole had arrested his girlfriend on drug charges days earlier. But he said the shooting wasn't a vendetta. He just wasn't ready to go back to jail on unrelated charges in Massachusetts. Williams was due in court that week to face those charges.

Friends who had seen Williams earlier in the evening reportedly told police that he had been doing drugs and was acting paranoid. After shooting Cole, he loaded his belongings into the fully marked Sheriff's Department pickup truck and drove to a convenience store in Norridgewock, where he can be seen on surveillance camera stealing water and cigarettes. The clerk called 911 and reported the stolen items and the regular customer in the sheriff's truck, and the manhunt was on.

Three days later, Williams was arrested in the woods in Fairfield, after a search that had included law enforcement from several other states and several federal agencies aiding police from Maine. Corporal Cole's handcuffs were used to subdue the man suspected of killing him.

John Williams has pleaded not guilty to murder. His trial is tentatively set for May of next year.
