Devin Moon called 911 on the afternoon of July 24 after she found the toddler cold and unresponsive. Reygan Moon was pronounced dead when paramedics arrived at Moon’s Lilburn home.
She told detectives that her daughter was born with a medical issue that prevented her from gaining weight. An autopsy did not find any disorder that would have caused such a condition. The little girl weighed just 14 lbs at the time of her death, half the weight of a normal 3-year-old child, according to the Centers for Disease Control and Prevention.
