Glover, 19, pleaded guilty in Richmond County Superior Court on Monday to a charge of felony murder. He was sentenced to life in prison.
His cousin, Rayshawn M. Ward, 17, is still awaiting trial for the Nov. 13, 2012, slaying of Demetrius Moore, 21.
Moore was the third shooting victim at the River Glen apartments in 2012.
Assistant District Attorney Rex Myers said Moore had been hanging out at the apartment complex gambling on dice games and selling marijuana. After he won about $400, several people in the area started plotting how to steal his cash and drugs, Myers said.
Glover and Ward, possibly with the help of 20-year-old De’John Grant, got to Moore the night of Nov. 13, 2012, Myers said. When they accosted Moore, he ran and Ward shot him in the back of the neck, Myers said.
Grant was shot to death on Dublin Drive on Dec. 1, 2012, possibly in retaliation, Myers said. Ward also was shot in the head but survived.
“I’m sorry for what happened to Demetrius,” Glover said. He had known Moore since they were little kids, he said.
