Abdul Emmanual was re-apprehended Tuesday, Rock Hill Police spokesman Mark Bollinger said.
Emmanual turned himself in over the weekend on an unrelated charge, but was released on bond Monday morning.
It was only after he was released, Bollinger said, that Emmanual was identified as a person of interest and later, a suspect.
Charges are still pending, but will likely mirror those drawn against Dontavion White, 17, and Mauriece Burris, 16. Both men are charged with murder, armed robbery, criminal conspiracy and possession of a firearm during a crime of violence.
Bollinger said investigators are still trying to determine the circumstances behind the shooting that left Michael Giddens, 25, peppered with bullets just before 2 p.m. Friday.
Giddens later died at Piedmont Medical Center in Rock Hill.
The three suspects fled the scene in a blue Mercury Mountaineer that was later recovered off Dave Lyle Blvd.
White and Burris turned themselves in to authorities Monday and remain in custody at York County Detention Center.
Emmanual will appear before a bond court judge on Monday.
