 As police there tried to conduct a traffic stop, the suspects sped away and crashed. That's when officers found the vehicle had been carjacked in Fairfax County earlier in the morning. The 16- and 17-year-old suspects were taken to a local hospital. Fairfax County police say two suspects first stole a Jeep that was left running at the Vienna Metro Station. Investigators learned that when that stolen Jeep became disabled, the suspects then carried out a carjacking along Porter Road in Merrifield. That driver was forced out of that vehicle at gunpoint.
