Second suspect arrested in Moses Lake shooting

A 16-year-old male was arrested Thursday in Moses Lake on suspicion of attempted first-degree murder in the shooting of Dale Olmos, 28, the Grant County Sheriff’s Office said.

Jose Rivera (pictured, left) is the second suspect in custody in Olmos’ shooting. The 28-year-old was found with a gunshot wound to the head in rural Moses Lake on Dec. 11 and remains in critical condition at a nearby hospital, the Sheriff’s Office said.

Police arrested Jordan Wiester, 21, on Wednesday. He is being held in the Grant County Jail facing charges of attempted first-degree murder and unlawful possession of a firearm.

The Spokesman-Review is naming Rivera, a juvenile, because of the severity of the charges against him. The hospital treating Olmos has not been released by the Sheriff’s Office due to security concerns because a third person of interest remains at large.

Investigators are still looking for Gilbert Williamson, 46 (pictured, left), in connection with the shooting. Williamson is described as a white man standing about 6 feet tall and weighing 220 pounds. His eyes are hazel and he has short brown hair, the Sheriff’s Office said.

Detectives think Olson was shot in a dispute over a stolen cell phone.

Anyone with information on Williamson’s whereabouts is asked to contact the Grant County Sheriff’s Office at (509) 762-1160 or send an email to
