Investigators baffled by the unexplained and gruesome deaths of Russian college students decades ago have come up with a new suspect, albeit an unlikely one: the Yeti.

On February 2, 1959, nine college students climbed the icy slopes of Dyatlov Pass in the Ural Mountains of Russia. They never made it out alive. The students bodies were found with broken ribs and fractured skulls. In one grotesque case, a woman's eyes had been gouged out and her tongue was missing.

At the time of the tragedy, investigators cryptically declared the Dyatlov Pass deaths were due to a "compelling natural force," according to a new television documentary reexamining the case.

Since the massacre occurred during the Cold War, some have speculated the students were killed by a top secret Soviet weapon. Others claim an indigenous tribe lashed out at the hikers for trespassing.

However, the murder site doesn't seem to jibe with those explanations:

A new documentary, "Russian Yeti: The Killer Lives" airing June 1 on the Discovery Channel explores the remote possibility that a "menk" -- the Russian word for Yeti -- may have been responsible.

They must have been teasing it. ;-) To read more and view the video, click here.
