WALLER, Texas – A warrant has been issued for a former Waller High School volleyball coach and biology teacher following allegations of an inappropriate relationship involving a student.
Joseph Anthony Mata, 28, is facing a felony charge of indecency with a child, according to court documents. He is accused of having sexual relations with a 15-year-old student.
According to Waller Independent School District representatives, Mata was terminated on Jan. 13.
Court documents state the alleged inappropriate contact between Mata and a teen took place in the “coach’s office” and “storage area” at the high school, as well as Mata’s apartment and car.
According to officials, the district received a tip on Jan. 5 via their anonymous reporting application, CrisisGo.
The district said an investigation was immediately opened with the Harris County Sheriff’s Office, and Mata was placed on leave the same day. His employment was terminated days later, officials said.
