A judge has sentenced a Fresno man to 780 years to life in prison on 34 counts of child sex and pornography charges.

Cornelio Jimenez was a registered sex offender who hid from police by lying about where he lived. Police said they found child pornography at his home.

Investigators found videos showing Jimenez engaging in sexual activity with two girls -- ages four and seven -- who lived in the home where he was secretly staying.
