In 2003 a congressional committee called the FBI's organized crime informant program "one of the greatest failures in the history of federal law enforcement." The FBI allowed four innocent men to be convicted of the March 1965 gangland murder of Edward "Teddy" Deegan in order to protect Vincent Flemmi, an FBI informant. Three of the men were sentenced to death (which was later reduced to life in prison), and the fourth defendant was sentenced to life in prison. Two of the four men died in prison after serving almost 30 years, and two others were released after serving 32 and 36 years. In July 2007, U.S. District Judge Nancy Gertner in Boston found the bureau helped convict the four men using false witness account by mobster Joseph Barboza. The U.S. Government was ordered to pay $100 million in damages to the four defendants.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many of the men died in prison?
