U.S. Attorney Thomas Walker said 28-year-old Hysen Sherifi was found guilty Thursday of nine counts related to the murder-for-hire plot. Sherifi will be sentenced in February, when he faces a maximum sentence of life behind bars.
Sherifi's brother and a friend also were charged in the murder-for-hire case and testified against Sherifi after reaching plea agreements with prosecutors.
Sherifi has said that he was arrested because of his Muslim faith. He was sentenced in January to 45 years in prison for plots to attack the Marine base at Quantico, Va., and overseas targets.
