Mark Hopkinson was executed by the State of Wyoming in 1992, and to this date is the only execution that has taken place there since 1965. He was convicted of four proxy murders but was executed for the one that was most personal. In this episode of Your Story or Your Life, I discuss his unique case and the current case of Lori Vallow and her daughter, who disappeared after visiting Yellowstone National Park with her mother and Lori's brother, Alex Cox. If investigators discover that Cox had killed the daughter on Lori's order, and while in Wyoming, then Lori could be in danger of capital punishment in the state. #Lori Vallow
