An interesting case of serial murder was reported from Sweden during 1948, wherein victims, selected apparently at random, were pushed from speeding trains at different points along the country's southern railroad network. According to police reports, released on November 29, there had been five such incidents -- all on weekends -- within the past five weeks. Four victims had died from injuries sustained in their falls, bodies recovered from trackside hours later; a fifth, prizefighter Carl Nilsson, managed to survive, but could remember no details of the attack. After ruling out accidental falls, police declared that they were searching for "a sadist." His -- or her -- identity may only be surmised, since no suspect was ever identified or brought to trial.
