One week after President John F. Kennedy was assassinated, a nation-wide poll revealed that 62 percent of Americans believed a conspiracy was involved. And now, over 40 years later, what do we believe?

A FOX News poll found that many Americans today do not believe Lee Harvey Oswald was a lone gunman. And there may be some evidence to prove it...

President Kennedy's assassination may have turned Dealey Plaza into the world's most famous crime scene, but in 1963 — crime scene investigation was not a sophisticated forensic science.

Cops made some surprising mistakes — mistakes that led to confusion for the investigators and fodder for conspiracy theorists.

Our special will examine the forensic evidence, the autopsy and the single bullet theory, including accounts from the people who were there.

You'll watch footage never before seen on TV and hear eyewitness testimony from people who've never spoken about it until now...

It's a one-hour special on American history that you don't want to miss... only on FOX News Channel.
