 Two Baltimore County Sheriff's deputies were transporting 28-year-old Joshua Brown in a marked SUV to the Baltimore County Detention Center on Friday, July 12th. Police say the vehicle was stopped as it was traveling northbound on Guilford Avenue and Mount Royal Avenue, and that's when Brown exited the rear passenger side door of the vehicle and ran west on Preston Street. The Baltimore County Sheriff's Office has issued a warrant for the suspect. At this time, police cannot say if there is any threat to the public.
