Gunfire erupted at an apartment complex in Federal Way, a city south of Seattle, and five people were reportedly shot to death, including a suspect who was shot by arriving officers, police said on Monday.

"When officers arrived there were still shots being fired," said Federal Way police spokeswoman Cathy Schrock.They found two wounded men on the ground in a parking lot. One of the men reached for a gun as police moved in to assist the two, she said.At that point, officers opened fire. The suspect died but police said it wasn't immediately clear if it was from their gunfire, the Los Angeles Times reported.

The other man on the ground and a third man in the parking lot were found dead.

In a search of the complex, police found a fourth man dead in one apartment and a murdered woman in another unit. Schrock said police were trying to determine if the woman was hit by a stray bullet.

A total of eight officers fired their weapons, Schrock said. All have been placed on administrative leave, per standard policy, as the investigation continues.

They said they did not think another shooter was on the loose, nor that an immediate threat was toward the public.

Federal Way is about 20 miles south of Seattle.
