PORT ORCHARD, Wash. (AP) — A shooting at a Walmart left one person dead and two sheriff's deputies wounded Sunday afternoon, a Washington state sheriff said.

Kitsap County Sheriff Steve Boyer told the Kitsap Sun that the two deputies and another person were being taken to a Tacoma hospital. Tacoma General Hospital spokeswoman Marce Edwards said three people had arrived at the hospital but she could provide no further information, including their conditions.

The incident began at about 3:45 p.m. and few details were known, including what sparked the shootings, Boyer said.

Witness Victor Meyers told KOMO-TV that the first shot was followed by six more in rapid succession.

"I heard one shot, which I thought was a car backfiring, and then several more reported back, which I knew to be gunfire," Meyers said.

He said he saw a female deputy running toward a victim on the ground before he and other witnesses were hustled from the scene.

The store was immediately locked down, and customers weren't being allowed to leave.

"No one is allowed in or out until further notice by police," customer Mike Lambert told KIRO-TV by phone from inside the store.

Port Orchard is about 15 miles west of Seattle across Puget Sound.
