A 15-year-old named Decorion Jones was shot on the south side of Pine Bluff, Arkansas, one Monday afternoon in November 2016. Responders found him with a gunshot wound and he was taken to a nearby hospital; he died the following Tuesday.

Police moved quickly. By the same day Jones died, a 17-year-old male had been arrested without incident and was being held on a charge of first-degree murder. Officials said they had not determined a motive at that time, and Jones’s body was sent to the state medical examiner for autopsy to establish the official cause of death.

Anyone who knew Decorion, or who has information about the shooting or its circumstances, is asked to come forward.
