HILLSBORO, Ore.- On July 31, 2020, a Washington County jury found Stephen Matthew Lister guilty of two counts of first-degree assault, two counts of unlawful use of a weapon and two counts of failure to perform the duties of a driver to injured persons. On August 6, 2020, Judge Ted Sims sentenced the defendant to 19 years in prison and ordered him to pay a $200,000 compensatory fine to the female victim in this case. Chief Deputy District Attorney Bracken McKey prosecuted the case against Mr. Lister.

On August 22, 2019, law enforcement received reports of a crash involving a vehicle and a motorcycle near SW 175th Avenue and SW Blanton Street in Aloha, Oregon. Callers reported the vehicle struck the motorcycle and that the driver of that vehicle then drove off without checking on the two crash victims, a man and a woman.

The Washington County Sheriff’s Office responded to the scene. Both victims were severely injured as a result of the crash. The female victim was rushed to the hospital and treated for a spinal injury. The male victim was alert at the scene and told officers that a man by the name of Matt Lister, who was later confirmed to be Stephen Matthew Lister, intentionally struck his motorcycle. The victim told deputies that he knew the defendant and was involved in a verbal argument with him shortly before the crash.

Responding officers quickly identified the defendant as a person of interest and began searching for him and the vehicle involved in the crash. The following day, Washington County Sheriff’s Deputies Thomas Bowler and Gene Mitchell spotted a man matching Mr. Lister’s description at a home in Aloha, Oregon as they were attempting to serve a search warrant on an unrelated case. They then spoke with the lead detective who secured the proper warrants needed to apprehend Mr. Lister. Officers approached the home and ordered Mr. Lister to come outside. After a brief standoff, the defendant was arrested.

The Washington County District Attorney’s Office acknowledges the work of all law enforcement on this case including Detective Mark Povolny, Deputy Bowler and Deputy Mitchell.
