Police in Arlington, Texas, say a high school math teacher is suspected in a string of rapes.
So far, 32-year-old Nicholas Wilborn has been charged with aggravated sexual assault and burglary. Police say they have D-N-A evidence against Wilborn.
An Arlington police spokesman says Wilborn is a "sexual predator" who was breaking into people's homes and threatening to kill them and their families, even young children.
Wilborn has taught ninth grade math at Duncanville High School since 2004.
Police arrested Wilborn after a woman reported an attempted break-in at her home. In his car, they found child pornography, still cameras, a video camera, a screwdriver, condoms, rope and duct tape.
