DOVER-FOXCROFT — Maine State Police have charged a Dover-Foxcroft man with killing his brother, who died in his parents’ yard after being shot in the head.

Steve McCausland of the Maine Department of Public Safety says 22-year-old Steven Mayo was arrested without incident at his home this afternoon.

The Medical Examiner’s Office says the victim, 20-year-old Ryan Mayo, died from a single gunshot wound to the head on May 1. The two brothers live adjacent to each other on French Road.

McCausland says detectives consulted with the attorney general and Medical Examiner’s Office about statements and evidence gathered over the past week. Mayo, who’s being held in the Piscataquis County Jail, is expected to make his initial court appearance on Monday.
