Three cases from The First 48 in which homicide suspects go on the run, rather than face the consequences of their actions. In New Orleans, it's all hands on deck for NOPD to find the two triggermen in a mass shooting on Bourbon Street. In Dallas, an escaped convict is suspected in a stabbing homicide and investigators are worried he might flee the country. And in Tulsa, a robbery gone wrong puts one suspect in the hospital and sends the other one into hiding.
