A 19-year-old man was killed in a multi-vehicle crash on the 101 Freeway in Encino early Saturday morning, April 25, 2026. The California Highway Patrol (CHP) is investigating the incident, with a focus on the possibility of driving under the influence (DUI) as a contributing factor.

Details of the Collision

The crash occurred at approximately 1:48 a.m. on the northbound lanes of the 101 Freeway near White Oak Avenue. Initial reports indicate the incident began when a vehicle collided with the freeway’s center divider and became disabled in the first lane.

Chain Reaction and Fatal Impact

A second vehicle, traveling at a high speed, struck the stalled car from behind. Two individuals exited their vehicles to assess the damage. Tragically, a third vehicle then collided with the involved cars, striking one of the individuals who had been outside their vehicle.

The situation escalated further as two additional vehicles became involved, resulting in a five-car pileup. Emergency responders arrived to find a chaotic scene and pronounced the victim, identified as Chaz Castillo by the Los Angeles County Medical Examiner, dead at the scene.

Ongoing Investigation

The CHP is actively investigating the cause of the initial collision with the center divider. Investigators are also examining the speed of the second vehicle and the circumstances surrounding the third vehicle’s impact. The presence of individuals on the freeway after the initial crash is also under review.

Evidence Gathering and Witness Appeals

Authorities are gathering evidence, including witness statements and vehicle data, to reconstruct the events leading up to the fatal collision. The freeway was temporarily closed in both directions, causing significant traffic delays.

Safety Reminders and Community Impact

This tragedy serves as a stark reminder of the dangers of impaired driving and the importance of safe speeds. The CHP emphasizes the use of designated drivers and alternative transportation when alcohol or drugs are involved.

The incident also highlights the risks of exiting vehicles on busy freeways after minor accidents. The CHP is urging anyone with information about the crash to come forward to assist with the investigation. The community mourns the loss of Chaz Castillo.
