Very few people know this but the Dallas PD solved the assassination the same day that it happened. About 15 minutes after the assassination happened two Dallas Cops Roger Craig and Buddy Walter were examining a bullet mark on the sidewalk down by the triple underpass. 15 minutes after the assassination happened Roger Craig saw Oswald walk down the Grassy Knoll and get into a tan station wagon and drive away. Later on that day at about 5 pm after Oswald was arrested Roger Craig identified Oswald as the same person he saw get into the tan station wagon earlier in the day. Buddy Walters said that earlier in the day he saw that same tan station wagon parked on Ruth Paine's driveway. Oswald replied" Don't try and tie her into this" she had nothing to do with it. So the Oswald that Craig saw wasn't the same Oswald that was arrested at the Texas Theatre. This proves the two Oswald theory. You can read Craig's testimony here. http://mcadams.posc.mu.edu/russ/testimony/craig.htm
I don't think that Craig ever said the station wagon was tan:
[Sheriff's Dep. affidavit, Nov 22, 1963] I saw what I think was a light colored Rambler Station [sic] wagon with [a] luggage rack on top
[CE1967 Nov 22, 1963] ...a white rambler station wagon...
[CE1993 nov 25, 1963] ...a white white Nash Rambler station wagon with a luggage rack on top...
[WC testimony, 1964]
Mr. BELIN - What kind and what color station wagon was it?
Mr. CRAIG - It was light colored--almost--uh--it looked white to me.
Mr. BELIN - What model or make was it?
Mr. CRAIG - I thought it was a Nash.
Mr. BELIN - Why would you think it was a Nash?
Mr. CRAIG - Because it had a built-in luggage rack on 'the top. And--uh--at the time, this was the only type car I could fit with that type luggage rack.
Mr. BELIN - A Nash Rambler-is that what you're referring to?
Mr. CRAIG - Yes; with a rack on the the back portion of the car, you know.
