A former San Antonio teacher will serve six-years in prison after confessing that he had sex with a student. The Bexar County D-A's Office says 45-year-old Jose Hernandez was sentenced Tuesday after his guilty plea to a charge of sexual assault of a child. Hernandez was a history teacher and softball coach at Lanier High School when he and the girl had a series of sexual encounters at a motel in 2019. Hernandez was working at a middle school in the Hondo ISD at the time of his arrest.
