"I really think more people could easily have been shot with what this guy was doing. Customers ran for cover Sunday as the gunman opened fire inside the store, then tried to carjack a car at gunpoint outside in the parking lot. The carjacking victim who was shot by the gunman was airlifted to Harborview Medical Center in Seattle, where he is listed in critical condition. The armed civilians followed him to the parking lot where he shot a man while attempting to take his car. The identity of that hero customer who shot the gunman has not been released. "He is a hero," says Brian Adams, who was at the scene and saw the Walmart customer pull out his own weapon and shoot the gunman. The gunman tried to hijack a car - but when the driver refused to give it up, the gunman shot him. 'Hero' customer kills gunman during wild rampage at Tumwater Walmart 
 
 Police investigate shooting at Tumwater Walmart. Some people were moving more slowly, they were still kinda confused what was going on, so I just started shouting, 'go, go, go!'"
– Danner Barton's quick thinking meant he escaped an armed carjacking attempt Sunday with only a bullet wound to his hand. "I ducked my head and I gunned it" as the culprit opened fire in Tumwater, Wash., leaving a bullet lodged in his steering wheel, the 16-year-old tells KING5. Still, he's "super thankful" that a bystander eventually put an end to the violence. That bystander has not been identified by name, but he is a 47-year-old pastor and volunteer firefighter from Oakville, Wash. Police say the pastor shot and killed a carjacker identified as 44-year-old Tim Day in a Walmart parking lot—after Day attempted to steal three vehicles during a chaotic spree, say police. He was firing all the while, including inside the Walmart at one point. Another driver he shot remains hospitalized. Megan Chadwick had just escaped the store with her four kids when Day exited. "I thought we were in the clear … and then I just heard four gunshots in a row," she tells KOMO News. Day was shot dead as he fired on yet another driver, police say. "Without him how many lives could [Day] have taken?" Barton says of the pastor, who also administered first aid to the more seriously wounded driver. "He is a hero," says another witness at Walmart. At least one other bystander present also drew a firearm. "Those men who stood up, they are heroes to me," says Chadwick. Noting Day had a criminal history, police have related the episode to drugs and mental health issues.
