Tuesday evening, Sumter County deputies managed to get open a safe containing guns investigators say a teenager was trying to steal, when he killed two people in their home Friday night.
17-year-old Ruhemmeion King is charged with shooting Dallas Freeman and his mother Bonnie then lighting their house on fire.
Three other men are charged with theft by receiving stolen property, and more arrests are expected.
Investigators say all the suspects are part of a gang in Sumter County.
"We certainly believe part of the funding for the gang activity is, since they're not gainfully employed, they are, their job is to commit burglaries and thefts which furthers their criminal enterprise as a gang," said Sumter County Sheriff's Captain Ralph Stuart.
