CBS 58 reached out to the attorney representing Waterstradt who says that his family are devastated by the allegations and that he has no prior record or police contacts. 

"William is senior at Marquette University and is a track and field athlete and he has no prior record or police contacts.  He comes from a good family who are devastated by these allegations.  William and his family are taking these allegations seriously and I am in the process of obtaining police reports and other evidence.   William is presumed innocent and I would ask that the public withhold judgement until his case is resolved through the court process." - Attorney statement.
