Doctors accidentally killed a baby during delivery at a hospital in Aracaju, north-eastern Brazil.
The tragedy occurred after at least five doctors had tried for six hours to deliver the baby naturally.
They struggled as the baby boy's shoulders became stuck, inadvertently tearing off his head.
The 22-year-old mother told her family that she knew something was wrong when one of the doctors shouted 'Marcos, are you crazy?'
The baby's dead body remained inside the mother and had to be removed by Caesarian section.
The patient's family plan to sue doctors for medical negligence, saying the 5.4kg baby was too big for a natural birth.
