State Trooper Chad Walker no longer displays signs of viable brain activity and remains on life-support after being shot in the head and abdomen Friday night on U.S. 84 in Mexia.

DPS released the following Monday afternoon.

“After extensive life-saving efforts conducted by the Baylor Scott and White medical professionals, it has been determined that Trooper Chad Walker no longer displays signs of viable brain activity and he remains on life-support until he can share the gift of life as an organ donor. This final sacrifice embodies Trooper Walker’s actions throughout his life and service as a Texas Highway Patrol Trooper. The Walker family is grateful for the continued support and prayers as they remain at Chad’s side.”

Chad leaves behind his wife, a 15-year-old son and twin 7-year-old daughters, and a 2-month old daughter, all from Groesbeck. 

According to the DPS, Walker had stopped to check on a disabled pickup truck on the side of the highway around 8 p.m. on Friday, March 26 when the driver of that truck got out and shot at Walker multiple times.

The shooting suspect, DeArthur Pinson was found Saturday evening barricaded in a home off U.S. 84, where he was reported to have committed suicide.
