SC man faces sex assault charges over incident with nephew’s girlfriend

A Conway, S.C., man is in jail facing sexual assault charges stemming from an incident in which he is accused of assaulting his nephew’s girlfriend.

Conway police arrested William Mattson, 52, of Conway, on charges of criminal sexual conduct in the first degree in the reported rape of his nephew’s girlfriend.

A police report shows that the nephew had brought his girlfriend to his father’s house after the two had attended a New Year’s party. The nephew left and he told police he returned to hear moaning from outside the door of the room he shares with his girlfriend.

He told police he kicked the door down and found his uncle, Mattson, who also lives in the house, on top of his girlfriend. He claimed he drove his uncle from the home, striking him repeatedly.

While the nephew was giving his statement to police, the uncle returned to the home and told police his nephew had dropped the girl off and that he and the girl were drinking together. Mattson told police they began to hug and kiss while the girl was naked under a blanket, but that he was fully clothed. His nephew then returned and struck him repeatedly, the report states.

Police spoke to the girl, who said nothing was consensual. Mattson was then arrested.
