(CNN) -- Five people died late Sunday in shootings at an apartment complex near Seattle, including one man shot by police, authorities said.
When officers arrived at the scene in Federal Way, Washington, just south of Seattle, they could still hear gunfire, said police spokeswoman Cathy Schrock. They also saw two men lying wounded in a parking lot.
Police attempted to rescue the injured men, but one of them reached for a gun, and the officers opened fire, killing him. The second wounded man also died, Schrock told CNN affiliate KOMO.
Police then found a third body in the parking lot, as well as two more corpses inside the complex -- one man and one woman, who were in separate apartments. All of the dead were killed by gunfire, Schrock said.
No officers were injured.
Police do not know what triggered the shooting, which Schrock said was a gun battle involving the four men who died.
