In the spring of 2016 Chattanooga was hit by a sustained wave of gun violence that included the fatal shooting of 17-year-old Ladarious Bush. A Black male, Bush was inside a home on Seventh Avenue on the afternoon of April 18 when he was fatally shot. Authorities believed the killing was retaliatory, part of an escalating gang feud that had intensified after a rival gang member was killed days earlier.

Reports say Bush’s father was a high-ranking gang member and his older brother had been killed years before. Police also suspected Ladarious had been involved in at least two separate shootings in the two days before his death. The Chattanooga Police Department investigated, but the case went cold; no suspects have been publicly identified and no arrests have been announced.

If anyone knew Ladarious, who was spending time with him that week, or saw activity on Seventh Avenue around April 18, 2016, please share information with investigators.
