DES MOINES, Iowa (AP) — An autopsy shows a Rockwell City police officer killed during a standoff died from a gunshot wound to his chest. Gerard Meyers, assistant director of the Iowa Division of Criminal Investigation, says Monday the wound to officer Jamie Buenting was in the upper chest-lower neck region. The 37-year-old Buenting was shot early Friday as he and other officers attempted to enter a house to arrest 32-year-old Corey Trott, who was wanted on an assault warrant.

The Des Moines Register reported a complaint filed with Calhoun County District Court says Buenting was a few feet from the house when Trott fired a single shot from a .233 caliber rifle. Trott surrendered to authorities hours later. Trott faces a first-degree murder charge.
