Throughout history we have been confronted with criminal cases that just can't seem to get solved. In some cases a trial is held and a defendant is found guilty. In the rarest of cases the guilty party is ultimately put to death for the crime that they were convicted of. In a perfect world that would be the ideal judicial system. A fair trial and a righteous sentencing: But in the real world we often don't see that. We will look at five cases from the time before DNA evidence and hi-tech investigating tools. These cases have been a thorn in the side of the judicial system due to them not being solved, or of new evidence that may point to a different perpetrator than the one that was convicted. We will turn back the clock and look at these cases and see if we can find the unanswered evidence.
