THE FACTS:

On August 24, 2021 Seneca Alexander, who was 17 years old, and two of Seneca’s friends met with the defendant south of Gresham High School. The defendant got into Alexander’s car and asked for a ride to a nearby store. Surveillance footage showed the defendant wearing a covid mask for the entire encounter. Seneca’s friends did not know the defendant and were later unable to identify him. At the store, the defendant made a purchase and received cash back. He returned to the car and they drove back to the original meet up location. After a few moments the defendant got out of the vehicle and walked around to the open window of the driver’s side and began firing a gun. He fired 13 shots into the car. The sound was captured by nearby cameras which also captured footage of the defendant running away. Sentencing is set for July 24, 2026 at 1:30 PM.
