Legal manouvering over John E. Robinson and his potential execution could send the convicted serial killer from Missouri back to Kansas. Robinson, who was convicted of killing three women in Kansas and admitted to killing five women in Missouri before stuffing his victims’ bodies into barrels, was sentenced to death in Kansas. Federal prosecutors charged Robinson with an additional death penalty-eligible crime in Missouri after the Kansas Supreme Court ruled the Kansas death penalty law was unconstitutional. The U.S. Supreme Court, however, overturned that decision. So, prosecutors now want to drop the charge in Missouri and send Robinson back to Kansas to be executed. Robinson’s lawyers say they will oppose the request.
