A New York man was arrested on Thursday after telling a news station that he killed his elderly parents in 2017 and buried their bodies in the backyard. On Thursday, Lorenz Kraus, 53, went to WRGB and told anchor Greg Floyd that he killed his parents, Franz and Theresia Kraus, out of mercy. WRGB reported that one body was discovered on Wednesday, and the other was found the next day. “I did my duty to my parents,” Kraus commented.
