Update, Aug. 16: Carl Gershman, president of the National Endowment for Democracy, identified the passenger who died as Suvash Darnal, a Nepalese grantee of the NED.

Gershman said Darnal was a “wonderfully good and generous” person whose death is a “tremendous loss.” He called Darnal a “great human rights defender” who was “working for a new democracy” in Nepal.

The injured passenger was taken to a hospital.

Macadolf Hoffman, 59, of Woodbridge, the driver, was charged with reckless driving, a misdemeanor, said airports authority spokesman Rob Yingling.

The eastbound Dulles Access Road is closed near the Trap Road overpass as authorities investigate a fatal accident involving a SuperShuttle van, a Metropolitan Washington Airports Authority spokesman said.

The van ran into a jersey barrier on the roadway around 7:30 a.m., killing one passenger and injuring another, said Rob Yingling, the spokesman. At the time of the crash, there were four people aboard the SuperShuttle, including the driver.

The injured passenger was transported to a hospital, Yingling said.

Police are conducting a reconstruction of the crash, so the roadway could be closed for some time, Yingling said. Traffic is being diverted onto the Dulles Toll Road near the accident, according to Yingling.

Yingling said it was too early to say what caused the crash. Authorities did not release the identity of the victim.
