Pursuit leads to stand-off in Larson Community; suspect in custody

MOSES LAKE, Wash. (17AUG2018) – A 38-year-old Moses Lake man is in jail this afternoon after leading deputies on a high speed chase and then barricading himself inside his own home.

Robert Gwinn was noticed by sheriff’s deputies as he drove near Roads L and 5-Northeast just east of Moses Lake. Gwen was wanted for outstanding misdemeanor warrants and was to also be served with a protection order.

Gwinn at first pulled over for deputies, but then led deputies on a five-mile chase at speeds reaching 100 miles per hour. On two occasions he aimed his vehicle at deputies who were setting up spike strips.

Gwinn then abandoned his vehicle in the Larson Community and took off on foot. A short while later a deputy watching Gwinn’s house saw Gwinn enter the back door of the house in the 1000 block of Vandenburg Loop Northeast. Gwinn at first refused to come out when directed by deputies.

The Moses Lake Regional Tactical response Team, Moses Lake Police K9 Chief, and Sheriff’s K9s Chicka and Chewbacca also responded to the scene and surrounded the home. After about an hour, Gwinn came out of the home and surrendered. Gwinn is now lodged in the Grant County Jail for outstanding warrants and attempted assault on police officers.

Matthew Valenzuela, 33 of Moses Lake, was also found inside the home. He is lodged in the Grant County Jail for several outstanding felony warrants.

“This was another great example of cooperation between agencies, which all came together to make sure this incident ended as safely as possible,” said Sheriff Tom Jones.
