Fatal Car Accident, Walnut Creek, CA

Fatal Pedestrian Accident, Near Highway 680 Walnut Creek, Kills One

Walnut Creek, CA – On the morning of April 2, 2023, at approximately 5:42 AM, a grave incident occurred at the intersection of Treat Boulevard and Alderwood Road near Walnut Creek, involving two vehicles that led to tragic consequences. According to the California Highway Patrol (CHP) Contra Costa, a Nissan van, occupied by a single individual, was stationary, facing westbound on Alderwood at Treat Boulevard. In a critical turn of events, the driver of the Nissan exited his vehicle and stood behind it, a decision that would have unforeseen repercussions.

At this juncture, a Honda Accord, also traveling westbound on Treat Boulevard, approached the stationary Nissan. The driver of the Honda lost control, resulting in the Honda striking both the Nissan and its driver, who was standing vulnerably behind the vehicle. The impact was catastrophic, leading to the immediate pronouncement of the Nissan driver’s death at the scene, while the Honda driver was rushed to the hospital with major injuries.

The victim was later identified by the Contra Costa Coroner’s Office as Sergio Quilici, a 34-year-old resident of Concord. This incident has not only left a community in shock but has also prompted an ongoing investigation by the authorities. Witnesses to this tragic event or those with relevant information have been urged to come forward and contact the CHP in Martinez, as efforts to piece together the moments leading to this fatal crash continue.

Earlier that morning, at around 4:30 a.m., a pedestrian was hit on the Southbound I-680 near Treat Blvd, leading to the closure of all lanes for several hours. The traffic was diverted, but the lanes were reopened by 6 a.m. This is a developing story, and more information may become available in the coming days.
