South African photojournalist Brent Stirton was recently interviewed by NPR about his work photographing endangered gorillas that were murdered in the Democratic Republic of Congo. His famous shot of a dead 500-pound gorilla being carried out of the Virunga National Park after having been shot by unknown assailants appeared in Newsweek in July 2007. It’s also part of National Geographic’s July cover story, which investigates the mysterious killings of seven mountain gorillas in what was supposed to be a protected sanctuary. The pictures are completely arresting and worth a look.
