BILLINGS, Mont. –  Garryowen man with two previous child pornography convictions faces at least 10 years in federal prison after pleading guilty to viewing child pornography on computers in 2010 and 2011.

Assistant U.S. Attorney Marcia Hurd says 42-year-old Jason Dean Pitsch pleaded guilty Wednesday. U.S. District Judge Jack Shanstrom set sentencing for May 9.

Prosecutors say Billings investigators noticed that a specific computer address had child pornography movies to share and tracked the computer to Pitsch's mother. Hurd says Pitsch was living with his mother and acknowledged using the computer to watch child porn.

The Billings Gazette reports Pitsch was convicted for child porn in 1998. He was still on probation when he pleaded guilty to possessing child pornography in 2004. He was released from prison in 2009.
