Fairfax County police arrested a man in the June 2010 murder of 19-year-old Vanessa Pham.
U.S. marshals picked up 27-year-old Julio Miguel Blanco-Garcia, of Falls Church, Thursday shortly after noon at a house under construction in Vienna, where Garcia was working. They turned him over to Fairfax County police. He was charged with murder and questioned.
Pham was found dead on Arlington Boulevard in Falls Church, Va. Her car was found in a ditch.
She had trauma to her upper body, but the injuries were not consistent with the crash itself, police said.
In surveillance video showing Pham driving her car at the Fairfax Plaza Shopping Center just before her murder, she did not appear to be in distress.
Investigators developed Garcia as a suspect earlier this week through analysis of forensic evidence, police said.
Lt. Col. James Morris, Fairfax County's acting chief of police, said they do not believe Garcia and Pham knew each other.
