Episode 3-13- Triple jeopardy? Tried three time for the same murder. 1985 Fort Bragg N.C. A Soldier  tried three time for the murder of the same victim.  Once found guilty, on appeal a second trial was ordered. The suspect was found not guilty and acquitted.  A third trial was held.  With new information and evidence,  this time he is found guilty for murdering the same victim and given the death penalty.  How is this possible?  The founding fathers wrote that  a citizen would not be subjected to double jeopardy.  But do we have that here? Or do we? Look and listen closer to the situation and decide for yourself .
