Pablo Escobar’s hippos are wreaking havoc in Colombia

Columbia - Hippos once owned by Pablo Escobar are still roaming the grounds of the late Colombian drug lord's former home, presenting a problem for locals and wildlife officials, who aren't sure the best way to contain or control them.

The hippos were smuggled in as part of a zoo that Escobar built at Hacienda Napoles, his estate about 200 miles from Bogota. 

Escobar died in 1993, but his hippos remained on the land, even after the zoo's other animals were relocated.

Smithsonian magazine reports that hippos are believed to "kill more people each year than lions, elephants, leopards, buffaloes and rhinos combined."  More
