The Spokane County Sheriff’s Office has released images from security footage that clearly show a robbery suspect holding a gun Thursday afternoon at STCU’s South Valley branch.

One image also shows the customer who shot the suspect. A dark patch of what appears to be blood can be seen on the suspect’s Washington State University sweatshirt. Investigators also found blood at the scene.

The customer, a man wearing shorts and a blue T-shirt, had a permit to carry a concealed handgun, according to the Sheriff’s Office. It’s not clear whether he fired while the robbery was underway or when the suspect was running away.

Deputy Mark Gregory said he could not comment on details of an ongoing investigation.

“To use lethal force (citizens) must believe they are in imminent or immediate danger of death or substantial bodily harm,” Gregory said. “A citizen is no different from a deputy.”

The customer has spoken to investigators and retained a lawyer. He has not been charged with a crime.

The suspect was last seen running north, and deputies are searching for him/SR. More here (subscription required).

Question: Was the customer correct in shooting the robbery suspect?
