  • "The damaged muscles leaked out a protein called myoglobin, 'and it's too much for the kidneys to process. It causes the kidneys to fail,' which results in death, Oliver said.
    The muscle damage is called rhabdomyolysis, Oliver said.
    'Most of the time it's in (car) accidents or in people who freeze to death, and you get it in a lot of people who have prolonged seizures or in people who are in extreme physical activity like running in a marathon,' Oliver said. 'You see it in torture or child abuse and severe burns when the muscles get damaged.'"
