SAN ANtTONION -- A high school teacher in Edgewood ISD faces criminal charges after allegations of an inappropriate relationship with a student.
Memorial High School science teacher Marcus Revilla resigned this week and was arrested on charges of sexual assault of a child.
A 16-year-old girl told police she is four months pregnant and Revilla is the baby's father.
Police became involved after another student raised concerns to district officials about a possible relationship.
Edgewood ISD officials this week released a statement saying, in part, "the district consistently trains its staff to be vigilant... This is a case of a student taking care of another student by alerting school administration."
