An investigation of the killing of rare mountain gorillas has uncovered an inside job:

The Congolese Nature Conservation Institute (ICCN) is reported to have brought the charges against Honore Mashagiro – one of its members.

Ten gorillas were killed in 2007 in the Virunga National Park, a Unesco world heritage site.

The motive is said to have been related to creating a “distraction” while other illegal activity was conducted.
