Sunnyside police shot and killed a gunman who fired at officers in downtown Saturday night.

The shooting occurred at Sixth Street and Edison Avenue about

8:45 p.m., when officers stopped a vehicle that had been involved in gunfire moments before.

While officers were taking the vehicle’s occupants into custody, one of them took out a handgun and fired at the officers, according to a Sunday news release from the Sunnyside Police Department.

Officers returned fire, and the gunman was shot and killed. No officers were struck by the gunfire.

Phil Schenck, deputy chief of the Sunnyside Police Department, said more details about the incident will be released today.

It’s not yet known whether Saturday’s incident is connected to Thursday’s fatal shooting in Outlook.

“”I don’t want to speculate,”” Schenk said.

Sixteen-year-old Diane Lopez was shot after answering a knock on the door to the mobile home in which she lived at 10 First Ave. She died Friday morning en route to Harborview Medical Center in Seattle.

Investigators believe that incident was gang-related. They’re looking for four people who were wearing blue clothing and bandannas.

Meantime, the Washington State Patrol is conducting an investigation of Saturday’s shooting at the request of Sunnyside police.

The officers involved will remain on administrative leave during the investigation, in compliance with policy.

The officers involved are not being named at this time, pending the completion of the investigation, according to the news release.

The department also isn’t releasing the number of officers on leave, Schenck said.

Sunnyside officers were assisted by deputies from the Yakima County Sheriff’s Office as well as police from Granger and Grandview.

An autopsy for the gunman is scheduled for 10 a.m. today.
