The passer-by broke the window on the vehicle, removed the child and began performing CPR, police said.
Dallas Fire-Rescue confirmed that it was called to the school at about 1:30 p.m. When responders arrived, the child was unresponsive. Emergency workers continued CPR and transported the child to Baylor Medical Center, where she was pronounced dead.
Marks, a teacher at the elementary school, was interviewed by the Dallas Police Department on Friday afternoon.
Officials with the Dallas Independent School District said Marks has been placed on administrative leave and that a letter was sent home to parents about the police presence at the school.
