Grant Co. deputy, suspect both fired shots during arrest

MOSES LAKE, Wash. – A wanted suspect and a Grant County deputy both fired shots during an arrest on Sunday. 

The Quincy Police Department said the Grant County Sheriff’s Office was assisting bail enforcement agents with locating 42-year-old Robert Gwinn. Gwinn had outstanding felony warrants. 

Deputies learned he was at a home on Stratford Road around 1:15 p.m. They responded, saw Gwinn and when they made contact, he fired a handgun, according to Quincy Police. 

QPD said they know at least one GCSO deputy, later identified as Deputy Tyson Voss, returned fire. 

QPD said Gwinn then ran into a home, stole keys and a vehicle, and drove across a farm field towards Crab Creek. This led to a pursuit that ended with a PIT maneuver that made the stolen vehicle roll. 

Gwinn was taken into custody and treated for injuries. Medics later learned he had been shot in the shoulder. 

Gwinn was released from the hospital and booked into the Grant County jail. He was booked for his original felony warrants and new charges for 1st-degree attempted murder, 1st degree assault, 1st degree burglary and unlawful possession of a firearm 1st Degree. No deputies were injured. 

QPD is looking to get video released publically. The video must be reviewed by their citizen representatives before its release.

Per protocol, all deputies involved in the shooting are now on paid administrative leave pending the outcome of the investigation. QPD has not identified the deputy or deputies involved in the shooting. 

The investigation is being conducted by the Central Basin Investigative Team, comprised of officials from multiple police agencies.
