37-year old Michael Sparks went inside the Cricket Wireless store on South Broadway Friday afternoon to trade-in his cell phone.
Court records state he asked the clerk to transfer over pictures from his old phone to his new phone.
The clerk began to do that then noticed what looked like child pornography on the phone. She told police she finished transferring the photos and sent Sparks on his way.
A few minutes later, she called police and showed them the graphic sexual images of a man with a female infant.
Tuesday, police searched Sparks home on Dalton Ct in Lexington and confiscated a few items. Sparks now faces four counts of possessing child pornography.
