Auburn Police are waiting for a toxicology report on Richard Duncalf, the man shot and killed by Kent Police.

Detectives also are waiting for ballistics on the bullets fired by five officers and Duncalf.

Both reports will be issued by the Washington State Patrol crime lab. A toxicology report can reveal whether drugs or alcohol were in Duncalf’s body.

“We are waiting for toxicology report which can take at least a month and we are waiting for ballistics on the shell casings recovered which could take months for the WSP lab to complete that,” said Auburn Police Cmdr. Steve Stocker in a Wednesday email.

Auburn Police are investigating the shooting because Kent officers were involved.

Duncalf, 28, died from multiple gunshot wounds in the July 20 shootout in the 22900 block of 86th Avenue South. Bullets also struck a large propane tank that exploded. Four officers were treated and released that same day from Valley Medical Center in Renton for minor injuries from the explosion.

Kent Police placed the five officers on paid administrative leave, standard procedure in officer-involved shootings.

Officers responded to a report of a man with a gun at the Howard Johnson Inn on North Central Avenue, according to Kent Police. The man reportedly hit  an officer who showed up at the motel’s parking lot and brandished a firearm as he fled on foot.

After a 90-minute search, officers spotted Duncalf running between local businesses. Duncalf reportedly shot at officers who then returned fire.

Kent Police have not yet released the names of the officers involved in the shooting because of the ongoing investigation.
