Walker was shot multiple times after he stopped on the side of FM 2383 outside Mexia to help a person with a broken-down vehicle.

Governor Greg Abbott released a statement asking law enforcement officers to turn on their red and blue flashing lights for one minute on Friday to honor Walker’s life.

“Trooper Walker’s horrific murder is a solemn reminder of the dangers law enforcement officers face every day to keep our communities safe. We will always support law enforcement here in Texas, and we are indebted to the sacrifices that they make to serve and protect their fellow Texans,” said Abbott in a statement.

The shooter DeArthur Pinson Jr., allegedly shot Walker and then fled the scene. Pinson Jr. was found dead at a residence on Highway 84, west of Mexia, and Texas DPS believes he died of a self-inflicted gunshot wound.
