Ledbetter’s alleged accomplice Demarious Greene has not been indicted on the murder charges.
Two days before Ledbetter’s arrest, 21-year-old Greene was booked into Cherokee County jail on charges of robbery, aggravated assault and other counts.
Channel 2's Tom Regan reports suspects arrested in Woodstock could be involved.
The Cherokee charges are connected to when the men allegedly stole a man's necklace at gunpoint outside the Outlet Shoppes at Atlanta.
Ledbetter is also accused of a Sandy Springs necklace-snatching in which a woman told cops she was holding her 1 year old just getting home when a man snatched a gold chain off of her and the child.
Ledbetter is also wanted in Florida on an attempted murder charge.
His next court date was not immediately available.
