If he took the victim across state lines, the F-B-I could get involved in the sexual assault case against a former Beloit police officer.  Sixty-two-year-old Larry Woods is in custody for allegedly having sex with an underage girl more than 100 times.  Woods made a Rock County Court appearance Tuesday by video conference.  The victim is 14 years old.  Investigators say the assaults took place in hotel rooms and his S-U-V over a seven-month period.  Woods was arrested less than a day after the victim’s mother found some graphic videos on the child’s cell phone.
