PEARLAND, Texas – A mule had to be euthanized after it was severely injured when it was struck by a car on the Sam Houston Tollway Service Road west of Highway 288 overnight.

The driver told constables he was driving around 40 miles per hour and couldn't avoid the mule loose on the road.

The mule then took off westbound. Officers were able to stop the animal.

Animal control said the mule's legs had been broken and that it had to be put down.

It's not clear how the mule got loose or who owned the animal.
