RED OAK (CBSDFW) – An Ellis County coach was under fire from some parents this week for an in-school punishment, but investigators found she did not commit any crime.

Last Friday several girls were late to their 6th grade PE class at Red Oak Middle School. They were told by the coach to do “bear crawl” exercises across a hot field, which left their hands badly blistered. The coach was temporarily put on leave while the action was investigated.

“Fast forward to Monday, and our personnel investigation was still ongoing at that point,” says Adi Walker with Red Oak ISD. “Two parents involved decided they wanted to talk to the police department about pressing charges.”

Red Oak police and the Ellis County District Attorney’s office investigated and found no crime was committed.

Walker says the girls were taken to the nurse immediately after the incident, and Red Oak Middle School’s principal had let their parents know before the day was even over.

“We didn’t want the girls to go home and the parents then call to ask what happened. So we told them before the girls even got home,” Walker says.

Reaction from other Red Oak parents about the incident and investigation has been mixed.

The district’s separate personnel investigation expects to wrap up soon. The coach will be able to return to work after taking some time off from a death in the family.
