Dielman Calderon, Enrique Diaz-Mejia Obituary, Death – Authorities have released the names of the three men who were tragically killed in a violent crash early Saturday morning in Vallejo, California. The fatal accident occurred when the vehicle the men were traveling in collided with a parked car on Sonoma Boulevard near Valle Vista Avenue. Emergency responders were called to the scene shortly after 3:10 a.m.
According to the Solano County Sheriff-Coroner’s Office, the deceased have been identified as Dielman Calderon, 33, Enrique Diaz-Mejia, 21, and Cesar Ramos-Mejia, 34. Officials have not yet provided information regarding the men’s cities of residence. The Coroner’s Office has confirmed that Enrique Diaz-Mejia was driving the vehicle at the time of the crash.
When first responders from the Vallejo Police and Fire Departments arrived on scene, all three men were found unresponsive inside the vehicle. Officers immediately began life-saving efforts, starting with the removal of the rear passenger from the vehicle. At the same time, fire personnel began working to extricate both the driver and the front-seat passenger, who were trapped inside the severely damaged vehicle.
Despite the prompt and coordinated response from emergency crews, none of the three men survived. First responders were unable to revive them, and they were all declared dead at the scene.
The vehicle they were traveling in had reportedly struck a stationary vehicle parked along the side of Sonoma Boulevard. The cause of the crash remains under investigation. Police have not yet confirmed whether alcohol, drugs, or any other impairments were factors in the deadly collision. Authorities have indicated that further toxicology testing and crash reconstruction will be conducted to better understand the circumstances leading up to the accident.
The Vallejo Police Department is urging members of the public who may have witnessed the crash or have any relevant information to come forward. Officer Brad Kim is leading the investigation, and individuals with details are encouraged to contact him directly at 707-648-4329 or by email at brad.kim@cityofvallejo.net.
The crash occurred on a stretch of Sonoma Boulevard that is a well-traveled route through the city of Vallejo. Although it was still dark at the time of the collision, officials have not stated whether visibility, road conditions, or speeding played a role. What is known is that the impact was significant enough to trap two of the men inside the wrecked vehicle, indicating a high-speed collision or substantial force at the time of impact.
The sudden deaths of these three individuals have left a mark on the local community. While not much is currently known about the victims’ backgrounds or what brought them together early that morning, their lives were cut short in a matter of seconds in a devastating crash. Family members, friends, and community members are now left to mourn the loss of loved ones as investigators work to uncover what caused the fatal collision.
The Vallejo Police Department has not released information about the make and model of the vehicle involved, nor have they shared details about the parked vehicle that was struck. It’s also unclear whether that vehicle was legally parked, whether it was occupied at the time, or whether it sustained additional damage beyond the initial impact. Fortunately, there have been no reports of injuries to anyone outside the vehicle the three men were in.
This tragic incident comes amid ongoing concerns about traffic safety across California. In recent years, local and state authorities have been emphasizing the importance of safe driving habits, particularly during late-night and early-morning hours when visibility is lower and impairment-related crashes are more common. While there is no official word yet on what led to this particular crash, it has once again underscored the devastating consequences that can arise from a single moment on the road.
Authorities are expected to release additional details as the investigation progresses. In cases like these, investigators typically review surveillance footage, examine the vehicle’s onboard data, and await the results of toxicology reports to determine whether impairment or distraction played a role. Meanwhile, loved ones of the victims are beginning to come to terms with the loss, with tributes expected to follow as more information becomes available about the lives of Calderon, Diaz-Mejia, and Ramos-Mejia.
In the aftermath of the crash, police are also encouraging all drivers to remain cautious, especially when driving at night. They stress the importance of avoiding distractions, staying sober behind the wheel, and always being mindful of surroundings, including parked vehicles and potential hazards along the roadside.
As Vallejo mourns this sudden loss, police investigators remain focused on piecing together the final moments that led to the tragic crash. The community is left waiting for answers, hoping that the ongoing investigation will provide some clarity — and perhaps, a sense of closure — for those affected by this heartbreaking event.
