He was one of the leading JFK Assassination researchers in Dallas
during the 1980s and until his death. Larry ran the JFK Assassination
Research Center, in Dallas' West End. He was always available to assist
writers, students and just any passer-by that maintained an interest in
the murder of JFK. At the research center, he compiled and
administered a massive archive of files and other items relating to the
assassination. He once walked off during a live interview,
prime-time, on a major TV network, with himself and Marina Oswald,
because he felt he was not being allowed to fully develop answers to
questions by the interviewer. To his death, he maintained a strong
conviction that there was a Government cover-up in the JFK matter.
