Murder Mystery Viking Experiment

Murder mysteries streaming through the nation’s television channels have become a source of entertainment for some individuals; however, the officers that discovered the body of a local business man near Robins, NC were faced with the reality. The man’s cause of death was listed as drowning because he had a large amount of water located in his lungs. The water in the man’s lungs had a high concentration of phosphates.
