Tonight, tune in to The Kelly File for a one-hour special investigation of the facts of the criminal case surrounding the fatal shooting of an unarmed teenager by a police officer in Ferguson, Missouri.

What exactly do the eyewitnesses say and how does that differ from the police account? What is the hard evidence and whose version of events does it support?

Megyn will also examine the Missouri law on the use of deadly force – can the shooting be justified even if Michael Brown was unarmed?

Plus, she'll investigate suggestions that the DOJ seems to have drawn some of its own conclusions about what happened, even before the investigations are complete.

Check out a sneak peek clip above and watch the special hour, tonight at 9p/12a ET only on Fox News Channel.
