Glenn Brown was charged with murder after he walked into the Belfast Police Department to report the shooting.

State police say Brown killed Richard Bowden, 64, and Tina Bowden, 64, on Monday night at their home on Bonne Terre Road.

After Brown reported the shooting, medical personnel went to the house and transported Richard Bowden to Waldo County General Hospital, where he died.

Tina Bowden was found dead at the house, police said. The state Medical Examiner’s Office determined both died from gunshot wounds.

State police detectives and evidence response teams worked through the night at the house to process evidence and conduct interviews.

Brown will make his first appearance in Waldo County Superior Court on Wednesday afternoon.
