The young man who killed the biological daughter of rap star Juvenile has been charged with murder.

Anthony Tyrone Terrell Jr. was charged Friday in the deaths at the family home near Lawrenceville, where the bodies were found the night before, said police spokeswoman Illana Spellman.

Police say Terrell murdered his mother and two small sisters. The victims have been identified as Gwinnett County Sheriff's Deputy Joy Deleston, 39, and her two daughters, Micaiah, 11, and Jelani, 4. Jelani is Juvenile's daughter.

Deleston brought a paternity lawsuit in 2004, claiming that the 32-year-old rap star Juvenile, whose real name is Terius Gray, was Jelani's father, Gwinnett County court records show.

Attorney Randy Kessler, who represented Juvenile in the proceedings, said the case was resolved peacefully by consent order in 2006. Both parties agreed Juvenile was the father.

Kessler said Saturday he had not talked with the rapper about the killings. "Anytime you have a situation like that, it's shocking," Kessler said.

Terrell was taken to jail in neighboring DeKalb County to avoid any potential conflict because Deleston worked for Gwinnett County, Spellman said. He is being held without bail.

The motive was still unclear.
