NCIS Car Accident

As we first reported, a 52-year-old security guard working on the set was hit by a passenger van ... when the 60-year-old driver had some sort of medical emergency behind the wheel and veered on to the L.A. area set.

The security guard was rushed to a nearby hospital -- but later died from his injuries.

The driver of the van was also taken to the hospital and was later released.

We're told an investigation into the incident is still ongoing.
