Since sea turtle conservation in Costa Rica began in the 1950s, conservationists and poachers have peacefully shared the beach. But the murder of the environmentalist Jairo Mora Sandoval in 2013 shocked the eco-friendly country and brought attention to a violent overlap between conservationism and drug trafficking in Costa Rica's abundant national parks and untouched coastlines.
