More than two million declassified government files offer new evidence about Lee Harvey Oswald's activities in the weeks, months and years before the assassination of President John F. Kennedy with the last remaining documents scheduled for release later this year. HISTORY's new six-part nonfiction series "JFK Declassified: Tracking Oswald" follows former CIA agent, Bob Baer and former LAPD police lieutenant, Adam Bercovici, on their independent global investigation into Oswald, and the murder of JFK, asking the questions: did he have accomplices, and if so, who helped him assassinate the President?
