A former employee of the Social Security Office of Disability Adjudication and Review was sentenced July 30 in U.S. District Court in Seattle to five years in prison for receipt of child pornography, according to U.S. Attorney Jenny A. Durkan.

Thomas Joseph Barrett, 50, of Lynnwood pleaded guilty earlier this year following his arrest at work in January 2013. The investigation revealed that Barrett had accessed child pornography on both his work computer and at his home. U.S. District Judge John C. Coughenour imposed a 10-year term of supervised release to follow his prison term.

According to records filed in the case, SSA obtained evidence of inappropriate internet use by Barrett during work hours in November 2012 and immediately initiated an investigation. The Social Security Administration Office of Inspector General (SSA-OIG) investigated Barrett’s computer use, reviewing his internet history and examining his computer’s hard drive. The analysis produced evidence that Barrett had viewed child pornography using the computer. In addition, some of the website analysis revealed that Barrett had accessed news stories about the penalties for possessing and distributing child pornography. According to SSA, SSA’s network and data were never compromised.

Search warrants served at Barrett’s home and work revealed he had accessed more than 3,500 images of child pornography.
