The passenger of a car has died after the vehicle they were in struck a Fairfax County, Virginia, ambulance that was on its way to an emergency.

It happened Tuesday afternoon at Worldgate Drive and Alton Square in Herndon.

A Fairfax County ambulance with its “full emergency equipment activated” was trying to turn onto Alton Square, but the driver of a 2007 Hyundai failed to yield and struck the ambulance, according to news release from police.

The car’s passenger, 35-year-old Irvin Escobar Lujuan, of Sterling, was taken to the hospital where he later died. The driver, 23-year-old Jose Lopez Martinez, of Nokesville, was also hospitalized with injuries that were not life-threatening.

Speeding and alcohol appear to be factors in the crash, police said.

Lopez Martinez has been charged with driving while intoxicated.

Two first responders were also taken to the hospital with injuries that were not life-threatening.
