Beyond Belief: Fact or Fiction Forums

I'm not even sure if it was beyond belief....but like one of the stories was about a man who tried to steal the diamond necklace of his dead wife. He sneaks into the funeral home at night, but like, the wife, knowing his intentions and before she died, rigged a poison needle to stick him. He gets pissed off and stabs her several times. In the morning, detectives find him dead on the floor, they conclude that he died of a poisoning, but.... one thing doesn't seem right.... He has several scratches on his face... and there is skin under his dead wife's fingernails....I remember it was labeled true but it might be my mind screwing with me
