Montebello, California (January 10, 2026) — A predawn collision on the Pomona (60) Freeway in Montebello claimed the life of Aidan Guevara, a 26-year-old man who was killed after the sedan he was traveling in collided with a semi-trailer early Saturday morning, according to the California Highway Patrol and the Los Angeles County Office of Medical Examiner.
Incident Details: The crash occurred at approximately 3:04 a.m. in the eastbound lanes of the 60 Freeway near the North Garfield Avenue exit. CHP officers responding to the scene learned that Guevara was traveling in a white sedan that became involved in a collision with a semi-trailer, according to CHP Officer Sergio Garcia.
Montebello Fire Department personnel responded to the scene and pronounced Guevara dead as a result of injuries sustained in the crash. Authorities have not released details regarding the direction of travel of the semi-trailer, the specific sequence of events leading up to the collision, or whether any other vehicles were involved.
Due to the severity of the crash and the need for investigation, CHP issued a SigAlert at approximately 3:40 a.m., closing at least one lane of the eastbound freeway at the North Garfield Avenue exit. The closure remained in place for several hours while investigators documented the scene and crews cleared debris. The SigAlert was canceled at approximately 6:42 a.m., and normal traffic flow gradually resumed.
Guevara’s city of residence was not made public. No injuries to the semi-trailer driver have been reported.
Investigation: The California Highway Patrol is investigating the cause of the crash, focusing on vehicle positioning, speed, and whether the vehicles were stopped or slowing near the off-ramp. They will analyze scene evidence like vehicle damage, debris, and final positions. The proximity to North Garfield Avenue raises questions about merging, lane changes, and the role of the ramp in the collision.
Additional investigative steps may include reviewing electronic data from the semi-trailer, such as braking and speed information, as well as any available onboard or freeway surveillance footage. If the sedan was equipped with data-recording technology, investigators may also examine the vehicle’s data to gain a better understanding of the speed and driver inputs in the moments leading up to the impact. Because the crash occurred in the early morning hours, investigators will likely consider visibility conditions, lighting, and potential driver fatigue as factors in their investigation.
Legal Considerations: Collisions between passenger vehicles and semi-trailers often result in fatal injuries due to the extreme size and weight disparity between the vehicles. From a civil perspective, determining liability may involve examining whether either driver made an unsafe lane change, failed to maintain a safe following distance, or did not adjust driving behavior when approaching an exit ramp.
When commercial vehicles are involved, the analysis may extend beyond the actions of the truck driver to include the trucking company’s safety policies, training practices, and compliance with state and federal regulations. Issues such as speed management, route familiarity, and situational awareness near freeway exits can be central to understanding fault in these cases.
Pending the outcome of the investigation, Aidan’s family may consider pursuing a wrongful death claim to address funeral expenses, loss of companionship, and the emotional and financial consequences of losing a young family member. While no legal process can undo the loss, accountability can play an important role in providing answers and acknowledging what happened.
My deepest condolences go out to the Guevara family and loved ones during this time of tragic loss and grief.
