One guy he went missing for 30 years.

Why he was hiding himself, why he disappeared, nobody knows.

At the northern edge of India, attracting thousands of tourists every year, is the Parvati Valley.

Many come for the beauty of the Himalayas, others to party. But then there are some drawn in search of enlightenment, and this place changes them.

There are stories in that part of the world where they'll say like,

oh, the person didn't come back because they didn't want to come back.

Just to create a story and the scene, through all all this stuff along the river and then he just vanished.

The phenomenon, called India Syndrome, could be chalked up to the valley's spiritual allure.

But something else is going on here.

There's a string of disappearances, many foreigners, and nearly all of the cases, unsolved.

Bruno Musialik, a Polish national, is missing.

Odetta Houghton, 24 from camera...

...were mercilessly beaten to death.

Said he befriended a Baba.

Shortly after, Ian disappeared.

That valley is beautiful and enchanting, but it's very dangerous.

Nefarious things happen there.

I fell upon one of these cases of an American world traveler gone missing. The circumstances

of his disappearance were suspicious. So I flew halfway around the world in search of answers.

And what I found, I could have never imagined.

You could read his posts about the guru.

He knew this guy was bad news.
