From the testimony of George Michael Evica to the ARRB; March 24, 2007, Boston:
For the medical records at Parkland and Bethesda, no one has looked yet for the teaching institution records. Almost all of the doctors at Parkland and at Bethesda, many of them, had teaching institution connections, and some of them made reports to their teaching institutions; that is, as part of an internship, residency, et cetera.
I would make no assumptions. Find out every teaching institution that was involved with Parkland and every teaching institution that was involved with Bethesda, find out if there were any records distributed from both Parkland and Bethesda to those teaching institutions' files. I think you're going to come up with some very interesting material there.
Lastly, the Bethesda medical record - the last time that I interviewed Francis X. O'Neill, former FBI agent, he said at approximately midnight, he left Bethesda, the morgue room, where a fully-clothed body, presumably of John F. Kennedy, was in the coffin and the work largely, both of the autopsists and the cosmeticists, had been concluded.
Yet, sometime after midnight - I think after 1:00 - we know that at least two Secret Service agents saw an apparently naked John F. Kennedy on his face, and they were asked to verify a bullet hole in his back.
