A hippo is seen at the Hacienda Napoles theme park, once the private zoo of drug kingpin Pablo Escobar at his Napoles ranch, in Doradal, Antioquia department, Colombia on June 22, 2016. More than twenty years after drug lord Pablo Escobar died in a gunfight with police, a strange legacy survives him: his pet hippos. Escobar bought four hippos from a zoo in California and flew them to his ranch in the early 1980s. Left to themselves on his Napoles Estate, they bred to become supposedly the biggest wild hippo herd outside Africa – a local curiosity and a hazard. Estimates put them at about 35 in the area nowadays. (Photo by Raul Arboleda/AFP Photo)
