EVERETT — A Lake Stevens man was transported to a hospital with life-threatening injuries after an encounter with Everett police Thursday night.

The 39-year-old man got into an altercation with police around 5 p.m. near the intersection of 33rd Street and Broadway in Everett, said Shari Ireton, a spokesperson for the Snohomish County Multiple Agency Response Team (SMART). A police sergeant shot the man with a stun gun twice. The man began running, then collapsed.

Police administered life saving measures and requested aid units. The man was transported to Providence Regional Medical Center Everett.

Lake Stevens police were investigating him for unlawful possession of firearms. On Thursday, officers served a search warrant at his Lake Stevens house while a detective observed him at an appointment in Everett, according to a SMART news release. Knowing the man could be armed, the detective called Everett police for backup.

Four Everett police officers and a sergeant were involved in the Thursday night encounter.

“The suspect eventually left his appointment and started walking northbound on Broadway,” the news release said. “He was contacted by officers with Everett PD and an altercation ensued. An Everett PD sergeant deployed his Taser twice. The suspect began running away from the officers northbound on Broadway and collapsed. Everett PD immediately requested aid units and began to administer life saving measures.”

Police said they found two guns in the man’s possession.

SMART is a countywide task force of detectives that investigates cases in which police use potentially fatal force. The results of SMART’s investigations are forwarded to Snohomish County Prosecutor Adam Cornell, who determines whether the use of force is lawful and if charges will be filed.

This is the third case that SMART has been involved in this year. Last weekend, sheriff’s deputies shot and killed 44-year-old Ryan Hemmingson at an apartment south of Everett. And in May, Everett police reportedly exchanged gunfire with Jeff Phebus, shortly after he allegedly shot and killed his wife. Phebus, 57, was hit with a less-than-lethal round and survived his injuries.

SMART investigated seven cases last year.
