PROSSER, Wash. — The Benton County Prosecutor’s Office has dropped charges against a man accused of shooting a Prosser officer and an innocent bystander in Aug. 2019.

The suspect, Isaiah Colley, is still in jail for other charges. However, his original charge of assault in the first degree has been dismissed.

“The assault charges were dropped because police developed new evidence showing he appeared not to have been present at the scene at the time of the shootings,” said Benton County Deputy Prosecutor Brian Hultgrenn.

On Aug. 6, Ofc. Antonio Bustamante responded to reports of an attempted burglary at the Canyon Park Apartments off Canyon Drive and Anna Street. Police say the alleged burglars opened fire on Bustamante, shooting him in the leg.

The suspects ran off and were later identified as Abdiel Vargas and Isaiah Colley. Vargas was arrested that afternoon in Kennewick, while Colley was later found in Centralia. Both were charged with assault in the first degree.

Though the charges were dropped against Colley, he’s being held on another charge. Hultgrenn said he stole a gun from a witness related to the shooting. Colley is also facing possible bail jumping charges.

The case against Vargas is still moving forward, who pleaded not guilty to the assault charge.
