Ty Matlock told WTXS he was inside the store at the time. He said Walmart employees yelled for shoppers to leave the store, find an emergency exit or find cover.
“The screams that I was hearing were people who were like, ‘You need to stop. Back up. Go away. Get out of the way.’ Things like that,” Matlock said. “I had no doubt in my mind that he was gunning for people.”
After several minutes, Wilson drove out of the store and back into the parking lot, where he allegedly hit a parked car.
Wilson was arrested when he stopped at a nearby gas station.
San Angelo police said the truck was leaking fuel and officers had to activate emergency shutoff switches.
Police said Wilson showed signs of “excited delirium” and was taken to a hospital, where he was also combative with medical staff.
“From his behavior and everything involved in this incident, it's clear the suspect was under the influence of an unknown intoxicant,” said San Angelo police officer Tracy Gonzalez.
Wilson caused an estimated $500,000 in damage, but no one was hurt.
He is charged with criminal mischief and two counts of aggravated assault with a deadly weapon.
