SAN ANTONIO -

A 13-year-old girl used a cell phone to outsmart Enrique Morales, 37, and catch him exposing himself to her, San Antonio police said.

Morales was arrested Wednesday on a charge of indecency with a child for behavior that the girl said has been going on for years.

An arrest warrant affidavit stated that the girl told investigators Morales has not only exposed himself to her, but groped her and performed sex acts since she was about 8- or 9-years-old.

She said last Saturday she decided to catch the illegal action camera, using a friend’s cell phone camera to record Morales.

The affidavit stated the girl told police she could not use her own phone because Morales often checked it and she feared he would discover the recording.

The teen then took the video evidence to staff members at her middle school Wednesday and they called the police, the affidavit stated.
