“If I were to give a hypothesis… for the three men to die in the way that they did, something had to have been in their system. Whether or not it was taken knowingly, I wouldn’t answer that. But something was taken because three grown men do not freeze to death at the temperatures that were there at the time with just alcohol involved,” he told PEOPLE.
