A 40-year-old Tonawanda man was ordered by U.S. District Court Judge Richard J. Arcara Friday to serve a 10-year prison term and then be on supervised release for another 20 years on his conviction for distributing child pornography.

U.S. Attorney William J. Hochul, Jr. said that on Oct. 22, 2011 agents downloaded eight video files containing child pornography from Andrew Ortman’s home computer.

The computer was then seized under a search warrant and a forensic examination determined Ortman received and distributed more than 600 pornographic images.

Hochul said the case was brought as part of Project Safe Childhood, a nationwide initiative to combat the growing epidemic of child sexual exploitation and abuse launched in May 2006 by the U.S. Department of Justice.
