Kelvin Zaccheus Welch was 22 when he was fatally shot the evening of July 2, 2018, at a residence on Ryan Street in Savannah, Tennessee. Witnesses drove Welch to Hardin Medical Center; he was later transferred to a Nashville hospital where he died. The shooting reportedly followed an argument.

Investigators focused on 19-year-old Kentrell Siner, who admitted to shooting Welch but said he acted in self-defense, claiming Welch was trying to enter his home where his child was present. Siner was arrested on separate charges of tampering with evidence after an alleged friend removed the firearm, and investigators also charged him with possession of marijuana and drug paraphernalia found at his residence. Reports said several others on scene were arrested on outstanding warrants or drug charges.

Police repeatedly encountered uncooperative witnesses, which investigators said slowed the inquiry and increased reliance on forensic work. Initial reports did not indicate a murder charge; the matter was to be presented to a grand jury to decide whether the shooting was criminal or defensive. Does anyone who knew Kelvin or was in Savannah that night have information that could help fill gaps in this case?
