Michael Allen, a missing Portland musician whose body was recovered from the Presumpscot River Monday afternoon, took his own life, according to the state Office of the Chief Medical Examiner.

The medical examiner’s office confirmed Wednesday that the body found in Westbrook was that of Allen, who had been reported missing by family members Monday. The official cause of Allen’s death was drowning and the manner of his death was determined to be suicide, the examiner’s office said.

Allen, 37, was a lobsterman from Portland who played guitar in the local band Doubting Gravity.

He was last heard from on Friday, when he posted a message on his Facebook page, friends said Monday. Allen’s personal items, his money and his two vehicles were left at his home on Forest Avenue.
