Jury Finds Stephen Matthew Lister Guilty of Multiple Charges Stemming from 2019 Hit-and-Run Collision (Photo) - 07/31/20

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. Chief Deputy District Attorney Bracken McKey prosecuted the case against Mr. Lister before Judge Ted Sims.

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.

A sentencing hearing will be held on August 6, 2020. The defendant will remain in custody until that time.

Two Defendants Convicted on Multiple Charges Related to Shooting Along SW Scholls Ferry Road (Photo) - 07/20/20

HILLSBORO, Ore.- On January 22, 2020, Cristy Anna Sisco pleaded guilty to second-degree assault and two counts of unlawful use of a weapon. On July 7, 2020, Ms. Sisco was sentenced to 70 months in prison by Judge Janelle Wipper. On July 2, 2020, Carlos Alberto Quebrado was convicted by a Washington County jury of second-degree assault, two counts of unlawful use of a weapon and fleeing or attempting to elude a police officer. On July 16, 2020, Judge Ricardo Menchaca sentenced Mr. Quebrado to 70 months in prison. Both defendants will serve three years of post-prison supervision upon release. Senior Deputy District Attorney John Gerhard prosecuted the cases against the two defendants.

On April 24, 2019, the defendants were at a sports bar along Highway 99 in Tigard, Oregon when they got into a verbal altercation with the two victims. The argument escalated and management ordered the defendants to leave the establishment. They left the building but waited in the parking lot until the bar closed. The victims then walked outside where Ms. Sisco began making derogatory statements towards one of the victims. Eventually, bar management ordered the pair to leave the parking lot.

Shortly after leaving the parking lot, the victims noticed the defendants following them in their vehicle along Highway 217 and along SW Scholls Ferry Road in Tigard, Oregon. The victims saw that Ms. Sisco was in the front passenger seat as Mr. Quebrado drove the vehicle. Eventually, Mr. Quebrado accelerated the vehicle to pull alongside the victims’ vehicle. At this point, Ms. Sisco was seated in the window frame of the front passenger door and began firing several rounds from a shotgun directly at the victims. One of the pellets struck a victim in the forehead and became lodged under her skin.

Officer April Keller with the Tigard Police Department happened to be in the area at the time and observed Ms. Sisco seated in the window frame armed with the shotgun. She immediately activated her lights and sirens and began pursuing the defendants. A short chase ensued. The defendants eventually abandoned their vehicle and fled on foot. They were both apprehended after a foot pursuit aided by canine units from the Beaverton Police Department and the Washington County Sheriff’s Office. Officers found the shotgun and a spent shotgun cartridge in the defendants’ vehicle.

The Washington County District Attorney’s Office acknowledges the work of the Tigard Police Department, including Officer Keller for her quick actions in helping to apprehend the defendants on the night of the shooting. This office also thanks Detective Dave Hockin of the Tigard Police Department for his investigative work on this case.

Both defendants will be transferred to the Oregon Department of Corrections to begin serving their sentences

Gregory Dennis Hall Found Guilty Except for Insanity of Murder (Photo) - 07/20/20

HILLSBORO, Ore.- On July 15, 2020, Judge Andrew Erwin found Gregory Dennis Hall guilty except for insanity on one count of murder with a firearm. Senior Deputy District Attorney John Gerhard and Deputy District Attorney Dustin Staten prosecuted the case against Mr. Hall.

On April 6, 2018, the defendant’s elderly father called 911 to report that his son shot him inside a residence on SW Hoodview Place in Beaverton, Oregon. Officers with the Beaverton Police Department responded and ordered the defendant to come out of the home. The defendant then exited the home and was apprehended by responding officers.

Beaverton Police then entered the residence and found the defendant’s father lying on the kitchen floor. He was suffering from several gunshot wounds. Police rendered aid and called for an ambulance. Unfortunately, the victim died as a result of his wounds before medics could reach the hospital.

Beaverton Police detectives gathered overwhelming evidence of the defendant’s guilt, including a written confession. Mr. Hall told detectives he was involved in an argument with his father which led to the shooting. It was evident that the defendant suffered from a chronic mental illness, but he told psychologists with the Oregon State Hospital that he killed his father out of anger.

It was undisputed that Mr. Hall killed his father, and the trial consisted of an inquiry into his mental state at the time of the killing. While doctors with the Oregon State Hospital determined that the defendant did not meet the criteria for a guilty except for insanity finding, ultimately Judge Erwin agreed with the defense psychologist that due, in large part, to a lack of adequate medication, the defendant was indeed guilty except for insanity.

This office wishes to acknowledge the work of Beaverton Police on this case, including Detectives Chad Opitz and Madalyn Brown.

A sentencing hearing is scheduled for July 29, 2020.
