Suspicious that a package shipped from Hong Kong might contain smuggled animals, U.S. agents who opened the package found three live king cobra snakes hidden in potato chip cans. The man who was to receive the package outside Los Angeles has been arrested on federal charges.Rodrigo Franco, 34, could face 20 years in prison on a charge of illegally importing merchandise, federal prosecutors said Tuesday. U.S. officials accuse him of violating the Endangered Species Act and falsifying records.The package had been sent via the U.S. Postal Service. Each of the deadly king cobra snakes that were sent to Franco's address were about 2 feet long, according to an affidavit filed in federal court. In addition to the venomous snakes, agents found three albino Chinese soft-shelled turtles when they opened the parcel on March 2.Agents who searched the package removed the cobras but allowed the turtles to be delivered to Franco's address the next day under controlled circumstances before carrying out a raid, the U.S. Attorney's Office said in announcing the charges.When agents from the FWS and the Homeland Security Department executed a search warrant at Franco's home, they found that the package had been left in what looked to be a child's bedroom. There, more animals were found living in tanks, including a baby Morelet's crocodile, two types of snapping turtles and five terrapins.Franco returned home while agents were at his apartment in Monterey Park. Under questioning, he told them he had received 20 king cobras in two earlier shipments — and that they had died, prosecutors said. But analysis of records on his phone led agents to believe that at least some of those snakes had survived, because Franco had mentioned feeding them and delivering five snakes.As for the location of those snakes, the suspect "said that one of his contacts in China had a cousin that flew to Los Angeles from Virginia, collected the snakes, and returned to Virginia," the federal affidavit against Franco states, noting that the suspect had claimed the snakes were dead.The package had initially been flagged by an agriculture specialist of Customs and Border Protection — who opened it under suspicion that it might contain drugs, based on the shipper's address. When they saw something moving, they called inspectors at the U.S. Fish and Wildlife Service.The shipper's address was also recognized by Fish and Wildlife Service Special Agent Stephanie Johnson, whose portion of the affidavit mentions having an online exchange with the Hong Kong provider last year that included an offer of selling venomous snakes.Johnson lays out the discovery in the court document:
