MADISON, Wis. -

A 30-year-old Madison man is facing charges for sexual assault of a child.

A criminal complaint details the allegations against Josiah Peeples.

The victim is reportedly a 15-year-old boy who told investigators that he met Peeples on Craigslist and the pair communicated, exchanging photos before a sexual encounter in May.
