A curious transcript purportedly about President John F. Kennedy's assassination has been discovered among boxes of memorabilia that were long forgotten in an old safe at the Dallas County district attorney's office.

While the transcript reads like a conspiracy theorist's dream — Lee Harvey Oswald and Jack Ruby plotting to kill Kennedy — the DA's top assistant said it's likely material for a proposed movie.

Other items found in an old safe on the 10th floor of the county courthouse include letters to and from former DA Henry Wade, the now-dead prosecutor in the Ruby trial,

Much of the attention is bound to focus on the transcript purporting that Ruby and Oswald met at Ruby's nightclub on Oct. 4, 1963, less than two months before the Nov. 22 assassination. In it, they talked of killing the president because the Mafia wanted to "get rid of" his brother, Attorney General Robert Kennedy.
