CORPUS CHRISTI (AP) — A former U.S. Marine must serve 62 years in prison in a Texas child pornography case linked to about 16,000 images found on his electronic devices.

John Anthony Perez of Aransas Pass was sentenced Wednesday by a federal judge in Corpus Christi. The 37-year-old Perez in May pleaded guilty to three counts of sexual exploitation of a child.

Investigators say Perez says he became interested in child pornography when he was serving in the military and deployed overseas.

Prosecutors say Perez was suspected of the sexual assault of three children. A March search warrant of his home led to the seizure of multiple electronic devices with thousands of pornographic images.

Investigators say Perez, who was sentenced to 750 months behind bars, was producing child porn.
