 A February 25, 1967 memo by Garrison investigator Lou Ivon to Jim Garrison states that he could not locate a Clay Bertrand despite numerous inquiries and contacts.In December 1967, Garrison appeared on a Dallas television program and claimed that a photograph taken in Dealy Plaza immediately after the assassination depicted a federal agent in plain clothes picking-up and walking away with a .45 caliber bullet.He said that the bullet was not entered into evidence for the Warren Commission and was proof that another gunman was involved in the assassination.
