While most of the deputy constables' injuries were described as ranging from scrapes to back injuries, one of them may have suffered a possible broken arm, according to authorities on the scene. A K9 officer was also on the scene and was checked out by a veterinarian. None of their injuries were believed to be life threatening.
The driver of the original vehicle that had been stopped was standing on the shoulder of the road when the crash happened and was seriously injured. He was transported to a hospital in critical condition.
One of the deputy constables was conducting a search underneath the engine compartment of a vehicle during the initial stop, according to Splendora police Lieutenant Troy Keller.
"He heard the impact, he held onto the vehicle and was moved with the vehicle," Keller said.
There was no indication the driver of the Tesla slowed down prior to impact and was believed to have been intoxicated, authorities said. The Tesla driver was not injured in the crash and was taken into custody on a DWI charge.
