He has been a JFK assassination researcher for about 15 years where he has focused on the issues connected to the chemical analysis of the ballistics material since 2000. Wexler has spoken on the subject at JFK Lancer’s NID twice, at the Wecht conference in 2003, and at the AARC conference in 2004, three of those times opposite Dr. Kenneth Rahn, NAA advocate, from the University of Rhode Island. Wexler has collaborated with chemist Tom Pinkston since approx 2000 on the same subject matter. Other Kennedy interests focus on Oswald, his background and associates leading up to November 22nd.
