The communications coordinator for the city of Richfield has resigned amid allegations of having and sharing child pornography on his home computer in Maplewood.

Scott Andrew Bradley, 36, had worked for the city almost seven years before resigning on June 30. The investigation remains underway and he has not been charged with a crime.

Maplewood police searched Bradley's home April 8, removing a computer, three hard drives, three flash drives, CDs, a camera and a modem. Dave Kvam, Maplewood's deputy police chief, said "well over 1,000 images of child pornography," including photos and videos, have been sent to the National Center for Missing and Exploited Children for analysis. The center acts as a clearinghouse for law enforcement on child pornography.

Kvam said the investigation is moving quickly and a decision on possible charges will come within weeks. Sharing child pornography is a felony.

Maplewood's probe began after a Minneapolis police computer expert who investigates Internet crimes against children discovered 21 child pornography files that were available for downloading, Kvam said. Those files were traced to a computer at Bradley's home.

Maplewood investigators talked with Bradley at his work site, Kvam said, and he told them that the computer was in his home.

On June 22, Richfield began investigating allegations against Bradley that could have led to discipline, City Manager Steve Devich said in a statement. That investigation was completed but no discipline was imposed before Bradley quit on June 30.

Bradley had never been disciplined as a city employee and had no other charges against him, the city statement said.

His phone has been temporarily disconnected.
