Federal charges have been added on top of state murder charges against four men accused of being members of the gang MS-13.
On Wednesday, a federal grand jury indicted the men on charges of conspiracy to destroy and conceal evidence in connection with the killing of 16-year-old Jacson Pineda-Chicas last year.
Maryland state prosecutors said Jose Domingo Ordonez-Zometa, of Landover Hills, Maryland, led others in killing the Virginia teenager.
Investigators believe all the suspects and the victim were members of MS-13.
Indicted by the federal grand jury are Ordonez-Zometa, Jose Rafael Ortega-Ayala, 28, of D.C., Jose Henry Hernandez-Garcia, 26, of no fixed address, and Kevin Alexis Rodriguez-Flores, 20 of Stafford, Virginia.
All four defendants are currently being held on state charges.
The federal charges of conspiracy to destroy and conceal evidence in connection with a murder carry a potential 20 year term.
