GREENSBURG, Pennsylvania — A man has been convicted of first-degree murder in the stabbing death of his father-in-law, whose body was found in an overheated car along a western Pennsylvania highway.
Jurors in Westmoreland County deliberated for about two hours Monday before convicting 41-year-old Michael Martin of Charleroi in the August 2013 slaying of 67-year-old Earl Weygandt. He faces a mandatory life term without possibility of parole.
Prosecutors said he lured the victim to Donegal Township by saying he needed a ride, then got into the sport utility vehicle and stabbed him nine times. Authorities said Martin was angry because Weygandt had stopped giving him money.
Martin contended that he acted in self-defense after the older man threatened him with a gun. Defense attorney Brian Aston said his client will appeal the conviction.
