The Burlington Police Department announced a second arrest in connection with the July shooting death of Hussein Mubarak in Burlington’s Old North End. Deon Mitchell, 19, of Winooski, was arrested Monday and charged with accessory after the fact for first-degree murder, police said in a Monday press release.
