Teacher, 49, arrested for having 'improper relationship' with male student

Mary Todd Lowrance, 49, a teacher at Moises E Molina High School, turned herself into Dallas Independent School District police on Thursday morning, according to Dallas ISD Police Chief Craig Miller.

Miller said the teacher had been in a relationship with a student for a couple of months.

It was also learned of the alleged relationship after Lowrance disclosed details to a coworker who then alerted a Dallas ISD officer.

If the student had been a juvenile, the case would have been handled by the Dallas Police Department, Miller said.

'When you get 160,000 students and 10,000 teachers, you hear a lot of rumors, and you have to investigate all of them,' said Miller.

'And in this case, there was something to it. The student has been offered counseling. We're doing everything we can for him as well.'

Miller said that after Lowrance's coworker alerted authorities, it prompted an investigation where interviews were conducted with Lowrance, the student and two witnesses. The Dallas ISD police then got an arrest warrant.
