A woman killed after two vehicles struck the Subaru she was in with her daughter and another man in Puyallup last week has been identified, according to the Pierce County Medical Examiner’s Office .
Mary Delreco, 64 of Orting, died from multiple blunt-force injuries near the 5700 block of 176th Street East on Jan. 17. Her manner of death was listed as an accident, the medical examiner said in a news release.
Delreco was the rear passenger of the car while her daughter was driving, according to the Pierce County Sheriff’s Department on Facebook.
Matthew Rousseau, the driver’s boyfriend, told The News Tribune on Friday that he was in the passenger seat of the Subaru and fled the scene after the crash. Sheriff’s Sgt. Darren Moss confirmed that investigators learned later a third person was in the Subaru who was witnessed running away after the collision.
Witnesses told deputies that the Subaru was traveling at high speed and went through a red light on 70th Avenue East. At the same time, a pickup carrying a man and his 2-year-old son, made a legal U-turn. The truck struck the driver’s side of the Subaru. A white van that had been following the Subaru crashed into it before driving off.
