After investigations, detectives concluded that the infant couldn’t have gotten into the position he was found in alone. They also said the mother’s statements did not match with the evidence found during the investigations.

“Investigators looked into several statements given by the mother and other evidence at the scene,” Bibb County Sheriff’s Office said on Facebook.

Bibb County coroner Leon Jones told the outlet that the boy’s death was “sudden.” Autopsy results are pending.
