LAKE CITY, S.C. -- Authorities say a 19-year-old man is charged with the shooting death of his uncle in Lake City.

Florence County Deputy Coroner Don Reynolds says 39-year-old Frederick O’Neil McMillan was found shot to death in the front yard of a Lake City residence around 1 a.m. Thursday.

Investigators say Reynolds was arguing with Lontorrio McKenzie just before the shooting.

McKenzie has been charged with murder. Deputies aren’t sure what led to the argument.

It wasn’t clear if McKenzie had a lawyer.
