A Georgia grand jury has indicted a 17-year-old suspect in last week’s fatal shooting of a baby in his stroller and in another unrelated shooting 10 days earlier in a robbery attempt.

The 11 counts returned Wednesday against De’Marquise Elkins include malice murder for the slaying of 13-month-old Antonio Santiago. The indictment says Elkins shot the boy in the face with a .22-caliber revolver while trying to rob the child’s mother in coastal Brunswick last Thursday.

The indictment charges 15-year-old Dominique Lang on seven counts including felony murder. Elkins’ mother and sister were charged with trying to dispose of the gun in a saltwater pond.

The indictment also charges Elkin with trying to rob a man at gunpoint March 11 and shooting the victim in the arm.
