NORMANDY, Mo. (AP) — St. Louis County Police say an autopsy done on an 18-year-old who exchanged fire with an officer had one gunshot wound under his chin.

Sergeant Brian Schellman with the department said in a news release that the county medical examiner’s office did the autopsy on Amonderez Green on Friday.

The autopsy showed Green had a gunshot wound under the chin, and the bullet recovered confirmed the round was fired from a .38-caliber revolver.

Green died early Thursday, 14 hours after a confrontation with a Normandy officer in which they exchanged gunfire but neither was struck.

Police say Green was suicidal and ran a short ways before shooting himself. The autopsy did not say whether Green’s death was from suicide.

Green’s father and others had questioned the Normandy police department’s account.
