The custodian of a small school north of Marshalltown has pleaded guilty to possession of child pornography. Fifty-two-year-old Leslie Ulric Beal entered a guilty plea to having “visual depictions” of minors engaged in sexually-explicit conduct. He was sentenced to 21 months in a federal prison. About this time last year, cops got a tip that Beal was a customer of a mail order company that sold illegal child porn. Beal was a custodian at Green Mountain/Garwin Elementary, and cops visited the school, them accompanied Beal to his house, where he admited having videotapes of child porn. Matthew Whitaker, the U-S Attorney for Iowa’s Southern District, says individuals like Beal who prey on “our most vulnerable citizens” will be fully prosecuted.
