The shooting and arrests are now part of a larger investigation that has identified at least 50 people who could face charges for gang-related activity, Lt. Scott Peebles said. He said two gangs are being looked at: Georgia Deadly Boys and P-Town.
Charged Wednesday with aggravated assault and unlawful street gang activity were: Treshawn Cummings, 17, of Augusta; Kenneth Anderson, 18, of Augusta; and an unidentified juvenile, Peebles said.
Investigators think Taylor's shooting on Monte Carlo Drive was retaliation for gunfire the night before. Two men were charged earlier this week in that death.
Brandon Ira Le'Keith Helm, 18, of Hephzibah, and Darian Deandre Postell, 19, of Hephzibah were charged with one count each of murder and possession of a firearm during the commission of a crime.
Helm, who has been identified as Taylor's shooter by police, and a juvenile were walking through the Pepperidge subdivision Monday night when they were chased and shot at because they were recognized as rival gang members, Peebles said.
"It has been learned that Helm believed that Taylor was one of the individuals who shot at him, and revenge for this incident was the motive for Taylor's murder several hours later," Peebles said.
"It's (Pepperidge subdivision) not necessarily a gang haven, but they do have a gang problem just like other areas in Richmond County have," he said.
