Bryan Christy, a journalist with National Geographic, was shocked when he found that population of elephants in central Africa fell drastically by 64% in last one decade.
In a bid to find out how 30,000 elephants were killed every year, Bryan came out with a unique idea that landed him in jail. His investigative story first appeared on internet on September 12, 2015.

Bryan thought of implanting GPS device in fake tusks to track their journey.
Christy's search ended when he met a taxidermist who worked at museum exhibitions.
When traveling with the tusks for further investigation, Bryan was caught at the Tanzania airport.
Later, he implanted GPS devices in the tusks to trace how were they smuggled. As he watched on Google Maps, he came to know that they were taken to South Sudan.
Later, the GPS device indicated that tusks were buried underground.
In his story, Bryan shared his experience and knowledge about poached tusks, and how smuggled tusks helped to fund terrorists' organisations.
"Poorly equipped park rangers try to defend poachers. In central Africa, as I learned firsthand, something more sinister is driving the killing: Militias and terrorist groups funded in part by ivory are poaching elephants, often outside their home countries, and hiding them in national parks. They're looting communities, enslaving people, and killing park rangers who get in their way."
During course of investigations, Bryan Christy found that ivories landed in China, where the price of ivory-made chopsticks was in thousands of dollars.
