BLOOMFIELD, Iowa (AP) — Authorities say a southeastern Iowa man who was killed in December died of gunshot wounds.

The Iowa Division of Criminal Investigation and State Medical Examiners on Tuesday released how 39-year-old Michael Thomas Goodwin Sr. died.

Davis County Sheriff’s Office deputies found his body on Dec. 13 after receiving a call asking that they check on the man at his home north of Bloomfield.

On Jan. 11, police charged a 16-year-old boy with first-degree murder.

The Associated Press doesn’t generally name juveniles charged with crimes.
