Ricardo Terrell was 26 when he was shot dead on February 19, 2016, in Belle Glade, Florida. He and his brother Antwon were sitting in a vehicle on Southwest Sixth Street near Southwest Avenue C when a man identified as Alton Johnson opened fire, discharging 31 rounds into the car and killing both brothers.

Investigators reported that a day earlier there had been an exchange of gunfire between Johnson and one of the Terrell brothers, an incident that appears to have preceded the ambush. The Palm Beach County Sheriff’s Office led the investigation and charged Johnson in connection with the killings.

What additional details about the motive, the earlier shootout, or witnesses might help complete the picture of what happened that weekend in Belle Glade?
