Authorities say a 19-year-old was shot to death Tuesday night in Concord, New Hampshire.
New Hampshire Attorney General John Formella initially said Tuesday that members of his office were responding to a report of a suspicious death of a man in Concord that night.
Wednesday afternoon, Formella's office said that the victim had been identified as 19-year-old Zackary Sullivan of Concord, and that he had died from a gunshot wound to the neck.
The manner of Sullivan's death was homicide, Deputy Chief Medical Examiner Dr. Mitchell Weinberg determined at an autopsy.
Investigators say all parties involved in the incident have been identified, and there is not believed to be an ongoing threat to the public.
No further details have been released.
The Concord Monitor reported that a large police presence was seen at the intersection of Manchester Street and Old Turnpike Road on Tuesday night. Officials said Wednesday that police were expected to continue working in the area around Garvins Falls Road and Manchester Street for a period of time.
