Fresh look at DNA of 5000-year-old 'Iceman'

It's a cold case that's sparked great mystery and intrigue for decades. Way back in 1991, hikers found a mummified body trapped in the ice of the Italian Alps - they had found Ötzi the Iceman, who lived over 5,300 years ago. A new study of ancient DNA extracted from Ötzi's pelvis suggests he still has some secrets to give up.
