In 1993 Peter was accused of groping Natalie Kuijvenhoven (a former Miss Nebraska) in a crowded bar. He pled guilty and was sentenced to 18 months probation, and was suspended for a 1993 exhibition game. Following the 1993 charges from Kuijvenhoven, Kathy Redmond, who attended the University of Nebraska with Peter, came forward and claimed that Peter had sexually assaulted her during their freshman year in 1991. No criminal charges were filed in the matter, but Redmond did file a Title IX suit against the University of Nebraska in 1995; the suit was settled out of court.
