Autopsy: Normandy 18-year-old had 1 gunshot wound under chin

NORMANDY, Mo. -- A St. Louis County medical examiner has said an 18-year-old who exchanged fire with an officer died from a self-inflicted gunshot wound, police said Saturday.

The medical examiner's autopsy concluded that Amonderez Green died after a single gunshot wound.

"The autopsy showed Green sustained one gunshot wound, which was located under the chin," St. Louis County police spokesman Brian Schellman said in a news release Saturday.

Ballistic evidence of the bullet confirmed the round was fired from a .38-caliber revolver, the same type of weapon police said Green produced Thursday when he was confronted by a Normandy officer after relatives of Green called authorities "seeking police and medical intervention."

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

The confrontation was near Ferguson, which is still on edge 14 months after the fatal police shooting of Michael Brown, 18, who was black and unarmed. Green also was black. The Normandy officer, a 12-year veteran of the department, is white. He is on paid administrative leave pending the investigation.

Police said Green was suicidal and ran a short way before shooting himself.

Green's father and others had questioned the Normandy Police Department's account, though Normandy police Cpl. Tameika Sanders has said there was no question Green killed himself.

Schellman said in the release the investigation still is active, and police are seeking information and witnesses in the case.
