TOLEDO, Ohio (AP) — A judge says a 17-year-old from Detroit will be tried as an adult in the shooting death of a 3-year-old who was riding in a car on an Ohio highway.

The decision came Tuesday after the boy’s father testified that he was driving his children home in Toledo after Thanksgiving dinner when another car pulled up and someone opened fire.

The father says the teen charged in the shooting had disagreements with members of his extended family.

The teen already had been charged with complicity to murder in juvenile court.

Police say 3-year-old Malachi Barnes was in the backseat of his father’s car on Nov. 22 when the other vehicle pulled alongside on Interstate 75.

The boy later died at a hospital.
