Ted S. Warren / AP Police officers walk near evidence markers at the scene of an overnight shooting that left five people dead at the Pinewood Village apartment complex in Federal Way, Wash.

Five people were killed in a shooting at an apartment complex near Seattle late on Sunday, including a suspect who was shot by officers, police said.

Officers were alerted to a shooting in progress at around 9:30 p.m. local time (12:30 a.m. ET) by an emergency call from the complex in Federal Way, which is between Seattle and Tacoma, police spokeswoman Cathy Schrock said in a statement.

Gunshots were still being heard when officers arrived at the complex, she added.

"As officers assessed the scene two males could be seen in the parking lot injured," Schrock said. "An officer attempted to rescue the men, and as the (police officer) approached, one of the males on the ground reached for a weapon."

This led to police officers firing on the suspects, she said. Three men were confirmed dead in the parking lot, and a woman and another man were found dead in a nearby apartment, police said.

No officers were injured in the incident, and eight police were placed on administrative leave after the shootings. This is standard policy for officers involved in shootings, Schrock said.

While there was no word on what caused the gunfire, police said they did not think another shooter was on the loose. Police said they would provide more information at a 11:30 a.m. PT (2:30 p.m. ET) press conference.
