Nephew beats Uncle to a pulp after he caught him raping his girlfriend

This is a mugshot of William Mattson,52 , a South Carolina man who was caught red-handed allegedly raping his nephew’s girlfriend on January 1st.

The lovers reportedly returned home after a New Year’s party and the dude left the girlfriend alone in the house for a time. Upon returning, he heard “moaning” coming from the room he shared with his girlfriend and saw his Uncle on top of his girlfriend.

 Enraged, he beat the Uncle blue and black, drove him from the home and thereafter called the police.

The nephew was not arrested as he was acting in defense of the victim. The uncle is now facing charges related to the alleged sexual assault.
