SAVANNAH, Ga. (AP) — Almost a week after a baby was fatally shot in his stroller, police in coastal Georgia are saying for the first time they believe the child and his mother were victims of a random crime.

Glynn County Police Chief Matt Doering told reporters Wednesday investigators are looking into the possibility that the killing of 13-month-old Antonio Santiago in Brunswick was gang-related. But Doering says evidence police have gathered so far doesn't support gang-related charges.

The child's mother, Sherry West, says they were attacked last Thursday after she refused to give money to two youths who approached them on the street. She says a teenage gunman shot her in the leg and shot her baby in the face.

Police have charged 17-year-old De'Marquise Elkins and 15-year-old Dominique Lang with murder.
