A Hendersonville man has been charged with four counts of sexual exploitation of a minor after at least 400 images of child pornography were found on a thumb drive at his home.

Brian Lee Busch, 61, was arrested at his Walnut Drive home after Hendersonville detectives received information that pornographic images depicting underage children had been found on an account linked to Busch.

Hendersonville detectives, with the help of the Department of Homeland Security, executed a search warrant on Busch’s home on Oct. 7, according to an arrest affidavit filed in Sumner County General Sessions Court.

After seizing evidence in the form of electronic devices, detectives discovered a thumb drive located in a locked gun safe after Busch provided the access code. The drive contained at least 400 images of child pornography.

In addition, “tens of thousands of images” were found on seized devices and will be processed and identified by Homeland Security, the affidavit states.

Police say they expect to bring additional charges once all of the devices have been analyzed.

Busch is being held in the Sumner County Jail a $250,000 bond. He’s scheduled to appear in General Sessions Court on Nov. 10 at 9 a.m.
