JACKSONVILLE, Fla. -

A 48-year-old Jacksonville man was found guilty Thursday of two counts of using a minor to produce images of child pornography, three counts of receiving child pornography and two counts of possessing child pornography.

Robert Cowan, a former middle school guidance counselor, faces up to 30 years in prison for each child pornography production count, up to 20 years for each receipt count and up to 10 years for each possession count.

His sentencing hearing has not yet been scheduled.

Cowan was arrested Aug. 18 on related state charges.

According to evidence introduced during trial, the investigation of this case revealed that Cowan, who had been employed in Duval and Nassau County public schools since 1993, had produced images of a 4-year-old child engaged in sexually explicit conduct.

Police obtained computer media from his home in north Jacksonville, from his office at Fort Caroline Middle School and from a storage shed in Jacksonville, prosecutors said.

Investigators said Cowan's computers, smart phone, external hard drives and other media contained hundreds of images and videos of child pornography, including those that he had produced.

Many of the images and videos were downloaded by Cowan from the Internet and stored on his computer media since July 2008, prosecutors said. They said many of the images depicted very young children being raped and sexually abused.
