Detectives from the Mercer County Homicide Task Force took the boy into custody at his home Tuesday morning, they said.
They filed a delinquency complaint charging the boy with killing 37-year-old Danavan Phillips during a fight the night before in the 100 block of Oakland Street, Mercer County Prosecutor Angelo J. Onofri said in a news release.
The teen, whom Onofri didn't identify because of his age, shot Phillips once under the chin, the prosecutor said, without discussing a possible motive.Responding officers found Phillips unconscious but breathing shortly before 6:30 p.m. Monday, Onofri said.
He was pronounced dead a little over a half-hour later at Capital Health Regional Medical Center in Trenton, the prosecutor said.
The Hamilton teen was being held at the Middlesex County Juvenile Detention Center in North Brunswick pending a closed-door hearing in the Family Part of Superior Court in Trenton.
Onofri's Homicide Task Force is handling the investigation.
