A youth basketball coach in Iowa admitted to sexually exploiting at least 400 boys after he was accused of secretly recording them showering and sleeping, CBS News reports. Greg Stephen, 42, allegedly kept the recordings on a hard drive with folders named for 400 minor boys, with each folder containing explicit photos and videos he had collected over the years through his administrative position as founder of the Iowa Barnstormers of the Amateur Athletic Union (AAU). He allegedly recorded players undressing and showering using disguised devices in hotel bathrooms, his home, and his lake cabin. The boys who participated in the program were between the ages of 9 and 17, and many of them reportedly have gone on to play Division 1 college basketball. Stephen was reportedly caught after his former brother-in-law found one of the disguised recording devices in his bathroom and alerted authorities. In a plea deal, he reportedly pleaded guilty to five counts of sexual exploitation of minors and one count each of possessing child pornography and transporting child pornography. He faces a maximum of 180 years in prison.
