On April 14, several boys allegedly saw Gregor videotaping them in the bathroom at a swimming competition in St. Charles. Authorities say the mother of one of the victims wrote down the suspect's license plate as he fled.
Once tracked down, authorities say, a computer at Gregor's home allegedly revealed hundreds of images of child pornography. Detectives also say they found several images of apparent hidden-camera videos taken in various bathrooms and locker rooms.
Gregor is free on bond. His next court appearance in DuPage County is scheduled for May 20.
