(DC News Now) -- The Fairfax County Sheriff's Office (FCSO) said it fired and charged a former sergeant for assaulting a suspect in the back of a cruiser. Sgt. Joshua Silver was captured on in-car video punching a handcuffed man who was arrested and brought to the Fairfax County Adult Detention Center on Sept. 11. In the video, the man was filmed yelling expletives at the officers with a spit bag on his head. Silver opened the door and the man demanded they take the bag off his head. Man charged in connection to loaded gun found in 6-year-old Orange Elementary student’s backpack "Quit shining that [flash]light on me boy," he yelled before spitting at Silver.
