Zech then over-corrected and ran off the road to the right. His car struck a fence and then traveled down and embankment before coming to rest in a field on its roof.

Authorities say a passenger in the car, 33-year-old Valerie Roush, was to taken to Inova Loudoun Hospital’s Cornwall campus for treatment of minor injuries.

Zech, who was not wearing a seatbelt, was flown to Inova Fairfax Hospital. He was last listed in serious condition.
