Passenger's astonishing journey: Flying to LAX without passport, visa, or ticket

A Russian man named Sergey Vladimirovich Ochigava arrived at LAX on an international flight from Europe without a passport, visa, or plane ticket. Despite being visible to many on the plane, he had apparently evaded security in Copenhagen, Denmark. Ochigava interacted with flight crew, ate meals, and spoke to other passengers during the flight. He only realized something was amiss when he tried to pass the examination by U.S. Customs and Border Protection. Ochigava claimed to have no memory of how he got to Copenhagen or how he went through security without a ticket. The incident has left officials confused, and Ochigava faces up to five years in prison if convicted.
