UPPER MARLBORO, Md. (WUSA) - FBI agent Adrian Johnson was found guilty on all counts in the 2011 death of 18-year-old Lawrence Garner, Jr., according to the Prince George's County State's Attorney's office.

A jury took two hours Thursday to convict Johnson of motor vehicle manslaughter, homicide by motor vehicle while intoxicated, causing a life-threatening injury while impaired by alcohol and related charges.

On Feb. 7, 2011, Johnson's vehicle, traveling 58 miles per hour in a 40 mph zone, struck Garner's car after Garner had turned left onto North Keys Rd. from a driveway in an attempt to get into the left lane. Johnson was later found to be intoxicated at the time of the collision.

Johnson faces a maximum of 13 years in prison. He will be sentenced Dec. 14. On Thursday, his bond was revoked and he was remanded into custody.
