A 5-month-old girl was taken to Baptist Medical Center in life-threatening condition after she was found not breathing in a Westside mobile home Wednesday afternoon, according to the Jacksonville Sheriff's Office.
Police were called to the home in Normandy Estates in the 8985 Normandy Boulevard about 2:30 p.m.
"No obvious outward signs of foul play at this point, however, we're interviewing witnesses and family members to try to determine what happened," Sgt. Steve Zona said.
Police said they're trying to figure out who had custody of the child and who was watching her at the time.
The girl was taken to Baptist Medical Center.
The Department of Children and Families was notified.
