A women reported missing after leaving her home following a domestic argument was found dead in the back seat of a Breckenridge Hills (Mo.) Police unmarked Chevrolet Caprice.

Leslie Wehmer, 41, had been reported missing Saturday. A traffic officer returning to work Monday opened the rear door of the black police vehicle and discovered Wehmer's decomposing body. She was last seen Thursday night.

The vehicle had not been driven since July 4 because the officer was in training, reports the St. Louis Post-Dispatch.

Wehmer's boyfriend, Dave Childs told the Post-Dispatch they were arguing because of her alcohol-induced hallucinations. She had suffered from a couple of alcohol-related seizures earlier in the week.
