Richland WinCo shooter to be committed after being declared insane

Bail for alleged WinCo shooter set at $500K

RICHLAND, Wash. — A man who shot a woman in the head at the Richland Winco in 2018 will be committed indefinitely after being declared legally insane.

Matthew McQuin, 45, of Umatilla was arrested on July 30, 2018 after prosecutors said he shot a 33-year-old customer while she was reaching for a bag of bagels at the store off George Washington Way around 7:40 p.m.

When police arrived at the store, employees pointed to McQuin, who had sat down on a bench until officers arrived.

Security cameras captured footage of the incident.

After the shooting, McQuin told police he thought the victim was following him and believed she was going to attack him with a chemical spray, court documents said. McQuin was known to have a history of mental health issues.

On Thursday, after a series of mental health evaluations, a judge declared McQuin legally insane and ordered for him to be committed at Eastern State Hospital.

Prosecutors say he will stay there until he is “no longer a danger to the community.”
