Substitute teacher accused of sexual assault of child

SAN ANTONIO – A 75-year-old substitute teacher accused of sexual assault of a child has been charged.

Police said Luis Lopez worked at the Northside Independent School District. He was also a tutor.

The investigation began after the family found a diary of the 11-year-old victim. Inside were details of what was going on.

That's when the family decided to take their findings to the principal of the school, who in turn called police.

Officers were able to get a search warrant for Lopez's home, but they didn't find him there. Instead, investigators tracked him down to a hotel with his belongings.

Police said Lopez worked with NISD for three years. He is charged with sexual assault of a child.

Investigators believe the alleged sexual assaults happened over several months, many of them over the summer.
