Get to know the story of Ötzi the Iceman, a 5,300-year-old glacier mummy who researchers discovered had been murdered.

--

In September 1991, two hikers discovered a corpse emerging from the ice. Researchers soon realized they were looking at the mummified body of a man who’d lived about 5,300 years ago, and theorized he got caught in bad weather and froze. However, a shocking discovery revealed his true cause of death and upended his story. So, how did he die? Albert Zink uncovers the truth about Özti the Iceman.

Lesson by Albert Zink, directed by Andrew Foerster, Rewfoe.
