Dave O’Brien has researched the JFK assassination since age 13 in 1965. In 1968, he formed a 'pen-pal' relationship with Dr. Malcolm Perry, the first doctor to treat JFK. He is one of few researchers ever granted access to the 'Oswald' window when it was locked and sealed to the public. Dave is back to discuss witnesses such as Bobby Hargis and evidence in the assasination like the Altgens 6 photo and medical evidence materials.
