BARBERTON, Ohio — A Barberton man will spend the rest of his life in prison for murdering his mother and living with her corpse for nearly six months.

Michael Petrie, 33, was found guilty of aggravated murder, murder and abuse of a corpse in the case.

Prosecutors say in mid-October 2012, he killed his 67-year-old mother by striking her on the left side of the head and neck with the butt of a sai, which is a traditional martial arts weapon consisting of a pointed baton with two curved prongs sticking out of the handle.

Petrie also stabbed her in the face and heart.

The body was not discovered in the home until April 2013. Petrie lived in the home for the majority of that time.

Petrie entered a not guilty by reason of insanity plea at his initial court appearance. The jury, however, found he was legally sane at the time of the crime.

Prosecutors say he will never be eligible for parole.
