SUMTER COUNTY, S.C. — A weekend shooting that left two men dead and at least three others injured was the result of rival gang activities, according to The Sumter Police. 

The incident happened around 1:00 a.m. Sunday at the Sunoco gas station at 1083 Broad St (Hwy 76) in Sumter. 

Gregory "Donta" Middleton, 30, and his cousin Michael Rogers, 30, both died from apparent gunshot wounds.

Diontrae Epps, 26 and Christopher Ford, 22, remain in a Columbia-area hospital in critical condition and a 19-year-old has been treated and released for minor injuries suffered in the commotion. 

Police believe a rap video titled "Boost the Murder Rate," which features one of the individuals involved, as well as robberies targeting rival groups led to the gunfire at the gas station.
