You're possibly aware that his name has cropped up in the JFK investigation because his fingerprint was identified as being present at teh crime scene (I think in either the Book Depository or the Dal-tex Building next door). Being a notorious hit man as well as Lyndon Johnson's known assassin of choice, it has always been a suggestive marker, especially regarding LBJ's direct involvement in the assassination (something that I think is clear as day but often ignored).I did not manage to find the name "Malcolm Wallace" (notorious FBI hitman) anywhere neither on this website, nor in the books concerning the Kennedy assassination, for example.
