A young boy was critically injured the morning of Nov. 1, following a traffic collision just north of Enumclaw.

The 4-year-old, Guillermo Silveria, died Saturday afternoon, according to a Washington State Patrol report.

The crash involved a small car, a sport-utility vehicle and a large semi pulling a trailer. The situation unfolded at 9:16 a.m. on state Route 169 at Southeast 383rd Street.

Traveling north on SR 169 were a 2007 Subaru Forester and a 2009 Honda Fit, both driven by Enumclaw residents. According to a press release issued by the WSP, Kassandra Silveria stopped for traffic and was struck in the rear by the Subaru. The Honda was pushed into the southbound lane, where it struck a Peterbilt truck hauling a “side-dump” trailer.

Silveria’s son was airlifted to Harborview Medical Center and she was transported to Harborview by ambulance. The driver of the Subaru was not injured, nor was the driver of the Peterbilt.

The WSP release cited “speed and inattention” as factors causing the collision and noted that charges were pending.
