A Hall County 911 recording reveals a desperate, but unsuccessful, attempt to revive a 9-day-old child who, authorities allege, was killed by her teenage mother. A male called 911 at 1:11 p.m. July 18, saying, “My niece, she couldn’t breathe and she’s turning yellow, and she’s not breathing and I have no heartbeat or anything.” “She’s not breathing at all?” asked the operator.
