PROSSER, Wash. — A second suspect accused of shooting a Prosser police officer and a bystander at an apartment complex early Monday has pleaded not guilty to his charges.

U.S. Marshals arrested Isaiah Colley, 19, in Centralia several hours after the shooting. He’s being held in Benton County Jail on a first-degree assault charge.

He’s also charged with jumping bail in connection with an unrelated case.

During his arraignment on Friday, a superior court judge set Colley’s bail at $550,000. The judge also imposed a no contact order for the bystander who was shot.

His trial is scheduled to begin on Sept. 16.

Colley and Abdiel Benjamin Vargas, 19, are suspects in the shooting of Ofc. Antonio Bustamante.

Bustamante was the first officer to respond to a report of an attempted robbery at the Canyon Park Apartments in Prosser just after 1 a.m. Monday.

Bustamante said he stepped out of his patrol car and heard 10 to 20 rounds of gunfire, police said. He suffered a gunshot wound to the leg.

A tenant at the apartment was also shot. Both victims are recovering from injuries that were not life-threatening.

Vargas was arrested during a traffic stop on Highway 395 near Clearwater Avenue on Tuesday. He has also pleaded not guilty to first-degree assault.
