The FBI lost fingerprints taken from the rifle agents found in the Texas School Book Depository after the president was assassinated in Dallas, new files have revealed.
At the time of the investigation in 1963, agents and outside experts concluded that a palm print taken from the barrel off the rifle belonged to Lee Harvey Oswald.
