A New York man killed his grandmother during an argument over what TV show to watch, police say.

Clarence Newcomb, 25, was arrested on Friday at the home he shared with Kathleen Newcomb, 82, in Kings Park, on Long Island about 40 miles east of New York City.

Local police say a man called them at about 4:35 a.m. to report the woman was lying on the floor.

Officers say they found Kathleen Newcomb dead when they arrived.

Medical officials haven't determined how she died. No weapons have been recovered.

Police say Clarence Newcomb told them he and his grandmother had argued over what to watch on TV.

Lieutenant Jack Fitzpatrick of Suffolk County Police says he doesn't know what television shows were involved leading up to the argument.

Newcomb is in police custody and could not be reached for comment.

Police say he is unemployed and it is unclear if he has an attorney.

He faces arraignment Saturday.
