In 1991, high in the mountains of Europe, hikers made a gruesome discovery: a dead man partly frozen in the ice.
The police investigation soon became a scientific one.
Carbon dating indicated that the man died over 5,300 years ago.
Today, he is known as the Iceman and nicknamed “Otzi” for the Otztal Alps where he was found.
Kept in perfect condition by the ice, he is the oldest complete human body found on Earth.
