A teenage girl and her parents are suing the Conroe School District, saying it failed to protect her from sexual abuse by a campus police officer.
The federal lawsuit seeks at least $2 million in damages.
It alleges the district violated the high school student's civil rights and also names ex-police officer Donald P. Mauro as a defendant.
Mauro was convicted of 18 counts of sexual assault in June 2005 after the girl and three other students said he had sexual contact with them on campus. Mauro is serving 44 years in prison.
The girl's Houston attorney Michael Josephson says his client now has severe emotional problems.
Conroe ISD attorney David Feldman says the district didn't know about the abuse and should not be held responsible.
