German tourist Lars Mitank, 28, was on vacation in Bulgaria when he got into a fight on the beach. He was taken to a hospital afterwards to be treated for a ruptured eardrum and given a prescription for antibiotics. He was told not to fly for a little while, so he told his friends to go on home without him and he stayed in Bulgaria. Alone in his hotel, Lars called his mother in a panic saying he was being followed by four men and told his mother to cancel his credit card. He was also paranoid about the prescription he was given, questioning what the drugs were really doing to him. Lars was last seen on video footage walking through the airport. Moments later, he is seen running in the opposite direction, having dropped his luggage; he runs full speed out of the airport and across the parking lot and to this day, has never been seen again.
