Calimesa, CA (September 9, 2025) – A tragic collision involving a Riverside County Sheriff’s deputy responding to an emergency call claimed the life of one person and left another seriously injured Saturday morning in Calimesa, authorities confirmed.
The fatal crash occurred at approximately 10:03 a.m. on September 6 at the intersection of Cherry Valley Boulevard and Roberts Street. According to the California Highway Patrol, the sheriff’s deputy was en route to a reported shooting incident with emergency lights and sirens activated when the crash took place.
While traveling through the intersection, the deputy’s vehicle collided with a second car under circumstances that remain under investigation.
The driver of that second vehicle, identified as 21-year-old Gavin Hinkey of Cherry Valley, was tragically pronounced deceased at the scene. A 20-year-old woman who was riding as a passenger sustained major injuries and was transported to a local hospital for treatment. Her current condition has not been disclosed.
The deputy sustained minor injuries and was treated at the scene. Officials confirmed the deputy was not wearing a seatbelt at the time of the crash. CHP reported that impairment does not appear to have been a factor in the incident.
The crash remains under investigation, with officials reviewing traffic camera footage, vehicle speeds, and the use of emergency equipment to determine the cause and assess protocol adherence.
We extend our deepest condolences to the family and friends of Gavin Hinkey and hope for a full recovery for the injured passenger.
Crashes Involving Emergency Vehicles in California
Saturday’s tragic incident in Calimesa shines a spotlight on the high-stakes challenges that surround emergency response driving—particularly at busy intersections. Crashes involving police, fire, or ambulance vehicles responding to calls are among the most complex in California due to their urgent nature and the legal allowances given to first responders under certain conditions.
In this case, the crash occurred while the Riverside County deputy was actively responding to a call with lights and sirens engaged. While emergency responders are permitted to proceed through red lights or stop signs during active responses, they are still required to do so with due regard for public safety.
Intersections like Cherry Valley Boulevard and Roberts Street present heightened risks, as cross traffic may not see or hear an approaching emergency vehicle in time to react—especially at higher speeds. The devastating outcome of this crash, which killed a young local resident and seriously injured his passenger, highlights how even lawful emergency maneuvers can lead to irreversible consequences.
Adding complexity, officials noted that the deputy involved was not wearing a seatbelt—a detail that will likely factor into internal reviews and potential procedural changes.
For victims and their families, the aftermath of such collisions often includes not only physical and emotional trauma but also challenging legal questions about responsibility, accountability, and long-term support. These cases frequently involve independent investigations and, in some instances, legal claims against public agencies.
Understanding your rights and options following a crash involving an emergency vehicle is critical. Whether pursuing answers, compensation, or support for recovery, families should not navigate these situations alone.
