This is a site that rates high for sixties' ambience—virtually nothing has changed in this musty, down-at-the-heels city building since that November day. The basement entrance to the ramp where police cars were waiting to transport Oswald to the county jail (which overlooks Dealey Plaza) is still accessible from inside the building if you act like you know where you are going. (Take the stairs at the left of the lobby to the basement and proceed down the hall to the glass doors, the only addition since the murder.)

SAYS JIM MARRS: Ruby was the mob's guy on the scene. He was the fixer. He knew half the police department and the District Attorney because they all went to his club and got free drinks. Ruby had run messages for Al Capone in Chicago when he was a kid. He was told by the mob that he had to shoot Oswald.

SAYS GERALD POSNER: Ruby was at the Friday night press conference and could have killed Oswald then; photos of the occasion show Ruby had a gun tucked into his waistband at the time. If he was part of a conspiracy, why did he wait so long to kill Oswald?

This grave is unmarked because vandals kept stealing the headstone. The only marker now is a flat gravestone; the grave is difficult to find and the cemetery will not direct tourists to the site.

SAYS JIM MARRS: When Oswald's body was exhumed, the funeral home said that this wasn't the same body they had buried. The concrete vault had been shattered and the body, which had been over-embalmed by the funeral home to preserve it, was decomposed.

SAYS GERALD POSNER: This is a really wild theory that shows there is no convincing a certain level of conspiracy enthusiast.
