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
