KITTITAS COUNTY, Wash. - Investigators have found and seized an abandoned semi truck that may have been involved in a crash that killed a young Everett woman last week on Interstate 90 in Kittitas County.

Washington State Patrol troopers said an unknown semi had rear-ended a Mazda driven by 20-year-old Shannon Prendergast in the Sept. 26 crash, and continued east on I-90 without stopping.

Investigators had no other information about the truck until a concerned passerby later noticed a parked semi at the Links at Moses Pointe and contacted the Grant County Sheriff's Office, said Trooper Brian Moore.

The Sheriff's Office contacted the State Patrol about the report, and investigators located the abandoned semi truck on Sept. 29. The truck had no license plates or any markings, such as decals, that would help identify the vehicle.

Reports said the semi truck was parked along trees, possibly in an effort to conceal damage on the driver's side. The State Patrol impounded the truck and are continuing the investigation.

The deadly accident happened at about 5:30 a.m. on Sept. 26 in the eastbound lanes of I-90 about 13 miles east of Kittitas.

A preliminary investigation found that the driver of a Dodge Ram pickup was heading east when he spotted an unknown animal in the road. He swerved, lost control and hit a guardrail, causing the vehicle to roll and land upside down in the eastbound lanes.

Prendergast's Mazda hit the pickup while it was upside down, causing the tailgate to become lodged in the car. The Mazda then continued heading east for nearly 2/10ths of a mile and struck a fence on the right shoulder.

That's when the unknown semi truck rear-ended Prendergast's Mazda and continued east without stopping. Prendergast was pronounced dead at the scene. The pickup driver, a 21-year-old Ellensburg man, was injured. He was taken to a local hospital.
