The former football coach at the University of St. Mary was sentenced Monday to 13 years in federal prison for trafficking in child pornography.

Scott Frear, 43, of Leavenworth, was sentenced during a hearing before U.S. District Judge Kathryn H. Vratil. He pleaded guilty in June, admitting he sent sexual images of himself and others to someone he thought to be a 14-year-old New Hampshire boy. The teen was actually a New Hampshire detective who was investigating computer sex crimes.

Frear, who sent the images in July 2005, was indicted by a federal grand jury in January.

Frear began coaching at St. Mary in 2002 and was the Kansas Collegiate Athletic Conference coach of the year that season. He previously was offensive coordinator at Avila University in Kansas City, Mo.

He resigned Aug. 16 from St. Mary, hours after university officials learned that he was being investigated.
