A Florida man's questionable conviction in a 1989 murder may be an example of what can happen when investigators disregard the venerable British mystery writer's caution. This Saturday, "48 Hours" correspondent Erin Moriarty reports on the case of Crosley Green. There is new evidence that Green may have been wrongfully convicted of the murder of 22-year-old Charles "Chip" Flynn more than 25 years ago. Green is currently serving a life sentence in Florida. Prosecutors and investigators in this case have faced allegations that they manipulated facts to fit their version of the truth - that Green committed the crime.
