A woman is dead after being struck by a Fairfax County Fire and Rescue vehicle in Reston, Virginia, Monday morning.

Those first responders were called to Laurel Glade Drive and Glade Drive just after 2:15 a.m. to help the woman, a spokesperson for Fairfax County police told WTOP.

A caller reported the woman was in an “altered state” and walking in and out of the street, police said. She was struck by an emergency vehicle as they arrived.

The first responders rendered aid to the woman and took her to the hospital where she died.

The road was closed for around two hours while police investigated the pedestrian crash but it has since reopened, WTOP Traffic reported.
