Mary Todd Lowrance (above), 49, a Texas English high school teacher was arrested after being accused of having an improper relationship with a male student over the age of 17, according to authorities . If the student had been a juvenile, the case would have been handled by the Dallas Police Department, Miller told The Dallas Morning News. '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. Miller said Lowrance has been on leave for several weeks while investigators worked on the case, according to NBCDFW. After she turned herself into authorities, she was booked into the Dallas County jail around 11am on Thursday on a $5,000 bond and was released at 4.40pm, according to county records. Calls made to the Dallas Independent School District police on Friday were not immediately returned to Daily Mail Online.
