Thom Berry, a spokesman for the South Carolina Law Enforcement Division, says Abbeville police were called to the complex around 3 a.m. Sunday.
They found four people shot.
The Abbeville coroner's office says two of them - 62-year-old Shirley Jean Jones and 26-year-old Steven Tinch - were dead when authorities arrived. The other victims were taken to the hospital where one - 24-year-old Johntavier Moss - later died.
Berry says authorities are currently looking for a suspect believed to have been driving a black Mitsubishi Eclipse convertible.
The suspect's name is not being released.
Berry says authorities believe the encounter began outside of an apartment in the parking lot.
