When the body of the Iceman was discovered, nobody realized that he had been murdered.
It was first believed that he got lost in a storm and had died in the cold weather.
However, with the discovery of an arrowhead in his body, it was clear that the Iceman was murdered.
Analysis showed that the arrow had entered his body and cut through an artery in his chest.
This would have caused severe bleeding and weakened him.
With the loss of blood, he couldn't have survived for very long after being shot.
Further examinations revealed something more about how he may have died.
Using a CT scan, scientists found blood in his brain.
This indicated that he was struck on the head before he died.
Either he was hit on the head or he fell and struck his head on a rock.
This probably happened when he was in a weakened condition after being shot by the arrow.
Additional evidence showed that the arrow itself had been pulled out of the body.
It had been pulled out with force, leaving just the arrowhead inside.
Even more interesting was what was left behind, the copper ax.
The technology needed to make such a weapon was new at the time.
As a result, scientists believe it was a sign of great wealth and position.
This suggests that the Iceman may have been an important leader.
It also raises the question of why the killer didn't take it with him.
（The killer left the copper ax behind even though it was valuable.）
