Calandra Nicole Troy, 39, was fatally shot in a drive-by shooting on Christmas Day in the Piedmont area just outside Bishopville. The late-afternoon attack also wounded her son; one of her children witnessed the shooting. Investigators say the violence grew out of a conflict between one of the suspects and Troy’s son.

Authorities identified two women, Tyuonna Dinkins and Ly’Nazia Nicole Williams, as the alleged perpetrators. Williams is believed to have been driving the vehicle and was arrested and charged with murder and attempted murder. Dinkins is accused of firing the shots that killed Troy and injured her son.

Two days later, what police describe as a retaliatory shooting left Dinkins wounded. Three people believed to have ties to Troy’s family were arrested on attempted murder charges in that incident; Dinkins was hospitalized and expected to be arrested and charged after her release.

If anyone witnessed the Christmas Day shooting or the subsequent retaliatory attack, can you share what you know with investigators?
