At least one of the citizens fired the shot that killed the unidentified suspect, who was in a Walmart parking lot in Tumwater, attempting to commandeer vehicles, Seattle's Q13 Fox reported, citing a police news release.
One of the victims, a man, was airlifted to a hospital, according to a police spokeswoman, Laura Wohl. Police say one of the civilians fatally shot the suspect.
Shortly after that, the man who is suspected of being the carjacker from earlier in the day began allegedly shooting at the Walmart. While officers were en route, they learned that a man had carjacked a vehicle belonging to the teenage girl at a nearby intersection.
A shooting outside a Walmart Supercenter in Tumwater, Washington Sunday evening was the end result of a crime spree from the now deceased gunman, police said. "Then the suspect tried to carjack a second auto".

Wohl said authorities do not yet know anything about the gunman and could not reveal any identifying details. "There were three civilians going after him to shoot him and two of them had their guns up and then the third guy shot him through the window of the auto".
Police say nobody inside the store was injured by the gunfire, which caused scores of panicked customers to flee through emergency exits. Wallner said as she ran out of the store she heard more shots. "Then it was like boom, boom, boom, and it was like "those aren't balloons" and we started running".
"All of a sudden, you hear this pop or a crash sound.About 15 to 20 seconds maybe even later, another sound exactly the same", said John Gerasimczyk.

Then, moments later, she heard a "pop, pop, pop" coming from what she said was the other side of the store, and she said everyone froze. "There were three civilians going after him to shoot him and two of them had their guns up and then the third guy shot him through the window of the auto".
