Read the two passages about Ötzi the Iceman. Half an hour after Ötzi dined, the killer came along and shot him in the back from a distance of almost 100 feet. The arrow went under his left armpit . . . a wound that would have been quickly fatal and probably not treatable even in modern times, especially where it happened. By the angle of the wound, he was either shot from below and behind, or he had been bent forward when he was hit from above and behind.

–"Who Killed the Iceman? Clues Emerge in a Very Cold Case,” Rod Nordland

Again pain pierced the right side of his chest. He only wanted a short rest, but his need for sleep was stronger than his willpower. . . . He turned on to his left side to dull the pain. He laid his head on the rock. His senses numbed, he no longer noticed the awkward position of his folded ear. His left arm, its muscles relaxed and probably slightly bent at the elbow, lay in front of him. His right arm was almost extended and was hanging down forward. His feet rested one on the other; the left shoe under the right. Soon his clothes froze to the rough ground. He was no longer aware that he was freezing to death. Overnight the body froze stiff.
