I can't figure out who's more messed up

A man apparently trying to seek revenge on an ex-girlfriend by sending child pornography featuring her and her son over the Internet pleaded guilty in federal court.

Antonio Perez III, of Harker Heights, pleaded guilty Thursday to one charge of transporting child pornography.

Perez, 21, was arrested after officers, acting on a tip received by Los Angeles police, searched his home and found computer equipment with images of a woman sexually assaulting her 2-year-old son.
