Fairfax County Police charged Evan D. Gargiulo, 22, of the 1700 block of Port Place in Reston, with the murder of taxicab driver Mazhar Nazir, 49 of Falls Church.

Police discovered Nazir dead inside his taxicab in the 8400 block of Greensboro Drive in Tysons Corner on Sunday, Nov. 2. Nazir died from a single gunshot wound to his head, according to autopsy results.

Gargiulo, a recent graduate of Pennsylvania State University, turned himself into Fairfax County Police at the Reston District station on Tuesday, Nov. 4 about 5:30 p.m. Police charged Gargiulo with murder and use of a firearm in the commission of a felony.

On Nov. 3, an anonymous caller contacted the Fairfax County Police Department’s Crime Solvers Unit and said Gargiulo committed the murder. On Nov. 4, detectives interviewed the caller, who told police that Gargiulo attended a Halloween costume party on Nov. 1 and Nov. 2, dressed in a wetsuit, a neoprene diver’s jacket, neoprene diver’s boots and a blond wig, according to Fairfax County Circuit Court documents.

Police filed search warrants last week in Fairfax County Circuit Court last week to permit them to search Gargiulo’s residence in the 1700 block of Port Place in Reston as well as his 2007 Nissan Sport Utility vehicle.

Gargiulo’s preliminary hearing is scheduled in Fairfax County General District Court for Dec. 22, 2008.
