SAN DIEGO (FOX 5/KUSI) — One person is dead after a helicopter crashed outside a small community near the U.S.-Mexico border in San Diego County Monday, Cal Fire confirmed. The crash was reported around 11:20 a.m. in a private field owned by the CBD farm, Sol Valley Ranch, near Round Potrero Road in the census-designated area of Potrero. The helicopter appears to have been an Airbus that departed Brown Field just after 9 a.m., according to the Federal Aviation Administration and the flight tracking website, FlightAware. At least one person sustained significant injuries in the crash and was pronounced dead at the scene, Cal Fire added. Their identity is not yet known. No further details about the helicopter crash, including whether it belonged to a federal agency overseeing border security, are available at this time. FAA and National Transportation Safety Board officials have been contacted to initiate an investigation, Cal Fire added. This is the second time a helicopter has gone down in San Diego County this year. The first, which was back in February, killed five U.S. Marines and prompted a massive foot search through East County during a heavy downpour of rain and snow. The aircraft in that incident was later identified as a CH-53E Super Stallion flying to Marine Corps Air Station Miramar in San Diego from a base in Las Vegas, Nevada. This is developing story.
