Five people were killed in a shooting at an apartment complex in the Washington state city of Federal Way -- about 20 miles south of Seattle -- the Associated Press reported on Monday, citing local police.
Police officers arriving on the scene shot a suspect, who has died.
According to the AP, the officers responded to an emergency call around 9:30 p.m. Sunday local time where they found two injured men on the ground in the parking lot of the apartment complex.
"When we arrived, there was a lot of gunfire already being fired," said Federal Way police spokeswoman Cathy Schrock.
As one of the men reached for a gun as police moved in to assist the two on the ground, officers opened fire, she said, the AP reported.
She said the suspect died but it wasn't immediately clear if it was from police gunfire.
The other man on the ground and a third man in the parking lot were found dead.
A fourth man was found dead in one apartment and a slain woman was located in another unit of the apartment complex.
Schrock said police were trying to determine if the woman was accidentally hit by gunfire.
It was not immediately clear what prompted the shooting in the first place.
No officers were injured, and the names of the five people who were killed have not been released.
