A man threw a microwave at his girlfriend, then fatally beat her after she refused to heat up sandwiches, police said.

Walter S. Fordyce, 58, of Uniontown, remained jailed without bond Thursday on a charge of criminal homicide. It wasn't clear if he had an attorney.

Fordyce told police he began arguing with his live-in girlfriend, Mary McCann, 58, early Thursday.

After throwing her to the floor, Fordyce threw a microwave oven onto McCann's chest after she refused to heat up sandwiches for him, he told police. Fordyce also said he stomped on McCann's chest repeatedly then banged her head on the floor until she lost consciousness — but that he also said he didn't mean to kill her, police said.

"It was an accident. I didn't do it on purpose," police quoted Fordyce as saying.

Fordyce ran to a neighbor's house for help, but couldn't find anyone there to call 911, police said. After returning home and checking McCann for a pulse — and finding none — he went downstairs and drank a beer before going to another neighbor's home and asking them to call 911, police said.

Autopsy results were not immediately available.
