Jackson County authorities responded to an emergency medical call about 4:15 p.m. Thursday and found a 10-month-old boy dead, Sheriff Mike Ezell said.
The infant was in the 9000 block of Jean Street in Latimer, he said.
Ezell said a man made the emergency call, but it's currently unclear who exactly made the call or his relation to the baby.
Coroner Vicki Broadus was on the scene.
The cause of death has not been revealed.
The Sun Herald will update when more information is available.
