A few minutes later, an officer arrived and exchanged shots with the gunman.
“I am told that there are quite a few shots,” she said.
Another officer arrived at the scene shortly after, and the gunman was killed at 3:48 p.m. Authorities have not publicly identified the man, saying he has yet to reach his relatives.
Lt. Borden identified the victim as Martin Haro-Lozano, a Walmart employee.
She said the sheriff’s office has yet to identify a reason for the shooting. She said the Walmart shooting was not linked to a shooting earlier in the day in Shingleton, California, in which three people were killed.
Walmart employee Scott Thammakhanty told The Record Searchlight, a newspaper in Redding, California, that he heard gunshots and saw people on the ground while he and other employees were running. He said the gunman looked familiar but did not know his identity.
A number of employees barricaded themselves in the back of the distribution center, according to radio transmissions from the police at the time.
Scott Pope, a Walmart spokesperson, said the company was deeply saddened by the incident.
“Our goal is to support our associates, as well as their families and colleagues at the facility,” he said in a statement. “This is an active police investigation and we will continue to work with the Tehama County Sheriff’s Office and assist them in their investigation in any way possible. “
Lacie Miller, the 37-year-old assistant manager of a nearby convenience store, said employees who gathered outside the building said the vehicle accident had caused a fire at the distribution center.
