Authorities confirmed Thursday six officers shot at a veteran suffering from PTSD Tuesday night near the Spokane Valley Mall.

The Spokane Investigative Regional Response Team's ongoing investigation into the killing of Army combat veteran Jed Zillmer revealed Thursday that Zillmer, who was wearing a ballistic vest, was holding a gun and two additional weapons were found on him.

Several additional weapons were visible inside his vehicle, though authorities have not yet processed his vehicle yet for evidence.

During the shooting, six Spokane County Sheriff's deputies fired their weapons, with the event being observed by officers from several local law enforcement agencies. The identities of those deputies who fired their weapons have not been released.

Detectives have finished processing the shooting scene for evidence and are now working to interview the deputies involved in the shooting as well as other witnesses. Investigators are asking that anyone who witnessed the incident or has additional information to contact Crime Check at 456-2233.

Zillmer, 23, was an Army combat veteran who was wounded in action in Afghanistan and, according to family members, suffered from PTSD.
