The investigation is complete in an officer-involved shooting this year, which resulted in the death of a suspected armed robber.
Stephen Corker, 30, was the suspect in a string of armed robberies at local coffee stands in the Spokane area.
He was shot when he stepped outside a home at Maple and Grace on March 26.
After the shooting police recovered several items in the home, including a semi-automatic handgun and several pieces of clothing described by the victims.
The Spokane Investigative Regional Response Team, which completed the investigation, is made up of detectives from the Spokane Police Department, Spokane County Sheriff's Office, Washington State Patrol and the Airway Heights Police Department.
