Cam Simpson is sat opposite a nervous-looking man in a stifling hot room in Jordan.

And he constantly asked my translator, you know, who is this guy? Who is this guy really? Why is he asking all these questions?

Cam has traveled nearly 6,000 miles across the globe to find this man.

A man he thinks can tell him about the fate of another.

A man who can explain how 12 men would wind up dead on the wrong side of the world.

Camandu. Cam works on all kinds of stories. He's covered topics from the exploitation of workers

making iPhones to hedge funds fueling repressive regimes. Like all good journalists, Cam is looking

He's listening out for what isn't being said in the news broadcasts.

These 12 men from Nepal had been kidnapped in Iraq

and turned into political theater against the U.S. occupation of Iraq.

And it was a terrorist group called Ansar al-Suna.
