URGENT UPDATE: An artillery shell detonated prematurely over California’s Interstate 5 on October 20, 2025, striking a California Highway Patrol (CHP) vehicle during a Marine Corps demonstration. Fortunately, no injuries were reported, but the patrol car sustained significant damage from the debris, prompting immediate investigations.
The incident unfolded during a live-fire event at Camp Pendleton, part of the U.S. Marine Corps’ 250th Amphibious Capabilities Demonstration at Red Beach. CHP officers were present to support a traffic break when the live shell detonated mid-air, creating a dangerous situation over a busy freeway.
“This was an unusual and concerning situation,” stated CHP Border Division Chief Tony Coronado, who is also an active Marine. “It is highly uncommon for any live-fire or explosive training activity to occur over an active freeway.”
In response to the incident, additional live-fire demonstrations have been suspended, and the Marine Corps is conducting a thorough investigation. Capt. Gregory Dreibelbis confirmed the situation and noted that the demonstration had undergone rigorous safety evaluations.
California Governor Gavin Newsom had preemptively closed the affected section of I-5. He criticized the decision to conduct the demonstration over a civilian route, stating, “This president is putting his ego over responsibility with this disregard for public safety.” Newsom expressed relief that no one was injured, adding, “This could have killed someone.”
The CHP is recommending an after-action review to improve coordination and safety protocols for future events near public roadways. An internal report has already been filed to address the planning and communication between federal, state, and local agencies involved in the demonstration.
As authorities investigate the specifics of the 155mm artillery round that detonated, the incident raises serious questions about safety measures in military demonstrations conducted near populated areas. The situation remains fluid, and updates will follow as more information becomes available.
This shocking event underscores the importance of stringent safety protocols in military operations, especially when they intersect with civilian life. The community is left shaken, and officials are under pressure to ensure that such a dangerous lapse does not happen again.
Stay tuned for ongoing coverage of this developing story.
