The driver in last month's fatal accident on Logmill Road in Haymarket has been charged with reckless driving, police say.
Prince William County Police say that 18-year-old Christopher Eduard Suarez of Gainesville is being held without bond.
Police say that Suarez was behind the wheel of a 2005 Dodge Magnum when it struck a deer, causing him to lose control of the car and hit a tree.
Two 15-year-old girls, Kendra Kaeleen Tucker of Gainesville and Savanna Kidane Mouratidis of Haymarket, died in the crash. A 14-year-old girl and 17-year-old boy from Gainesville were also injured.
The accident was one in a series of fatal incidents on that stretch of Logmill Road. Legislators approved $2.4 million worth of road improvements for the area earlier this week.
