A Renton police sergeant approached a man Thursday about a possible liquor violation and fatally shot him, after police said the man pulled out what appeared to be a shotgun.

The man was shot around 3:45 p.m. near 116th Avenue Southeast and Southeast 168th Street. The patrol sergeant radioed that he witnessed a liquor violation. Police said the man┬ápulled “what appeared to be a shotgun,” but dropped it and ran when the sergeant fired at least one round at him, according to a statement.

An officer arrived and fired a less-lethal round at the man, who police said “refused to obey commands to stop.” Police said the man pulled a knife and moved toward the officers, and that the sergeant fired at least one more shot to stop him.

The man was taken to Harborview Medical Center. Renton police spokesman Detective Robert Onishi confirmed he died.

The Valley Investigative Team is investigating the shooting, with the Port of Seattle Police as the lead agency.

The sergeant, who has worked for the department for more than 30 years, has been placed on administrative leave, as is standard for investigations of police shootings.

No officers were injured, according to police.
