On Saturday, 35 Jehovah's Witnesses gathered in their Kingdom Hall near Frankfurt and sat over coffee and cake (for whatever reason, maybe pioneer school or some other event). Suddenly a 20-year-old man (according to most sources "not a JW yet, but wanted to become one"; though one source claims that he would have been an auxiliary pioneer) took a knife from the cake buffet and killed a 45-year-old Bethelite (maybe a circuit overseer).
Today the murderer was killed by a train - supposedly suicide.
