'Shooter! Get out!': Tumwater spree leaves suspected gunman dead and one critically wounded

A shooting spree in Tumwater ended in a sun-drenched Walmart parking lot when an armed civilian shot the suspected gunman to death, police said Sunday evening.

Three people were hurt: a teenage boy with minor injuries, another person with minor injuries, and a man who was airlifted to Harborview Medical Center in Seattle. He is now in critical condition, Harborview spokeswoman Susan Gregg said.

On Monday, the Thurston County coroner confirmed the identity of the shooter as 44-year-old Tim O. Day of McCleary. 

Tumwater police spokeswoman Laura Wohl said officers first responded to reports of a vehicle being driven erratically. Then came reports of shots fired near Tumwater High School, where the teenage boy was hurt. Wohl said the gunman carjacked a vehicle and drove to the Walmart.

The gunman reportedly fired multiple shots both inside and outside the store, sending shoppers fleeing.

Megan Chadwick from Eugene, Oregon, was with her husband and four children inside the Walmart when the gunman entered.

"We were at the checkout and there is a flood of people running shouting, 'Shooter! Get out, get out!'" she said.

The gunman then attempted to carjack another vehicle and shot the driver, Wohl and witnesses said.

Wohl said at least two armed civilians followed the suspect out of the store and confronted him.

Brian Adams of Olympia said he was picking up pool supplies when he heard the shots and saw people running.

"He is a true hero because there would have been more victims," Adams said. "This guy was just shooting randomly in the parking lot."
