Are Some Sharks Feasting on Dumped Cocaine?

Marine biologist Tom "The Blowfish" Hird is investigating cocaine sharks for the Discovery Channel's annual Shark Week. He says fleeing smugglers being chased by the DEA are dumping significant levels of cocaine into the ocean which end up in the stomachs of sharks. Meanwhile, this is turning into the summer of sharks with five New York swimmers being attacked so far this year. Famed shark expert Paul de Gelder tells Inside Edition’s Alison Hall you should never take your eyes off a shark.
