A 21-year-old man was arrested Monday after a mother discovered inappropriate photos of him on her 16-year-old daughter’s phone.

The mother told East Baton Rouge Parish sheriff’s deputies that she was looking through her daughter’s phone and found the inappropriate images of a man later identified as Demerkus Joe Wiltz, a Sheriff’s Office report says.

When her daughter would not identify Wiltz, the mother gave the Sheriff’s Office consent to forensically exam the phone, the report says.

When interviewed by investigators, the girl told them she and Wiltz had been talking since she was 14 years old and that he was aware of her age, the report says.

The girl told investigators that she and Wiltz did not have sex until she was 16 years old and that it was only once. She told detectives that Wiltz had sent the photos to her.

Deputies attempted to schedule an interview with Wiltz twice but were unsuccessful.

Wiltz, 6211 Howell Range, was booked into East Baton Rouge Parish Prison on counts of carnal knowledge of a juvenile and indecent behavior with a juvenile.
