Three black men were killed and two others seriously wounded early on Friday, all within a 5km. The police are searching for a white man driving a white pick-up truck, who was seen in the area. More than two dozen officers are investigating the case, along with the FBI and U.S. Marshals. Four of Friday’s shooting victims were found in yards. Tulsa Police Chief Chuck Jordan said it was too early to know whether the shootings were ethnically motivated.
