Ötzi the Iceman froze to death

NEW ORLEANS — Ever since Ötzi’s mummified body was found in the Italian Alps in 1991, researchers have been trying to pin down how the 5,300-year-old Tyrolean Iceman died. It now looks like this Copper Age hunter-gatherer simply froze to death, perhaps after suffering minor blood loss from an arrow wound to his left shoulder, anthropologist Frank Rühli of the University of Zurich reported April 20 at the annual meeting of the American Association of Physical Anthropologists.

“Freezing to death is quite likely the main cause of death in this classic cold case,” Rühli said. Ötzi succumbed to exposure within anywhere from a few minutes to a few hours, he estimated.

New analyses of the Iceman’s body, based on X-rays and CT scans, argue against the idea that Ötzi died from a stone arrowhead shot into his shoulder (SN: 9/6/14, p. 6). Surprisingly shallow penetration of that weapon into Ötzi’s shoulder ruptured a blood vessel but caused no major tissue damage, Rühli said. Internal bleeding totaled only about 100 milliliters, or a half cup, he and his colleagues concluded. That’s enough of a poke to cause plenty of discomfort but not death, Rühli said.

Several depressions and fractures on the Iceman’s skull also couldn’t have proven fatal, he added. Some researchers regard those injuries as signs that Ötzi was clubbed to death. Rühli’s team found that those skull injuries are more consistent with the ancient man having accidentally fallen and hit his head while walking over rough ground. The Iceman was found with fur headgear that probably helped to protect his noggin when he took a headlong tumble, Rühli suggested.
