HILLSBORO, Ore.- On July 5, 2023, Washington County Circuit Court Judge Oscar Garcia found Mariano James Polanco guilty of Attempted Murder in the Second Degree, Assault in the First Degree, Failure to Perform Duties of a Driver to Injured Persons, and Driving While Suspended or Revoked. On July 7, 2023, Judge Garcia sentenced Mr. Polanco to 90 months in prison. Deputy District Attorney Sean Kallery prosecuted the case against the Defendant. 

On July 2, 2022, Mr. Polanco, age 45 at the time, parked his truck next to the victim’s recreational vehicle and began harassing him. He threw plastic bottles at his vehicle and played loud music. The victim, age 60 at the time, confronted the Defendant. The victim used his cane to try to prevent the Defendant from attacking him. The Defendant then kicked the victim away from the Defendant’s truck before exiting his vehicle, causing the retreating victim to hold his cane like a baseball bat to prevent the Defendant from closing the distance. 

The Defendant then told the victim he was going to kill him and that he was a dead man. Mr. Polanco got back into his truck, reversed it, and accelerated at a high rate of speed directly into the victim. He suffered serious injuries and had to be taken to the hospital.

Hours later, police spotted the Defendant in his truck and stopped him. They noted damage to the front of the vehicle consistent with the crime scene. They matched debris left at the scene to damage on the truck. They also used video captured days earlier of the victim’s truck to confirm the damage was caused recently. 

The Washington County District Attorney’s Office acknowledges Hillsboro police for their work on this case.

Upon completion of his sentence, the Defendant will also serve three years of post-prison supervision. Mr. Polanco will be transferred to the Oregon Department of Corrections to begin serving his sentence.
