HSCA Hearings - Volume II
Volume II of the HSCA hearings volumes consists of the proceedings of Sept. 11 through
15. 1978. The transcripts of these days includes testimony about acoustics evidence, trajectory
analyses, the testimony of accused assassin Lee Harvey Oswald's wife Marina, photographic
analysis, and testimony concerning Yuri Nosenko, a Soviet defector.
The testimony of Sept. 11 was concerned with analysis of an audiotape purported to have captured
the shooting in Dealey Plaza. It was recorded on a Dallas Police radio channel due to a stuck-open
microphone on a police motorcycle. The acoustic analysis showed at least 4 shots, with one of
these coming from the "Grassy Knoll." This conclusion was subsequently disputed by a panel
appointed by the National Academy of Sciences, but that rebuttal itself has been called into
question by a recent peer-review article by D.B. Thomas presented in Science and Justice
The Sept. 12 proceedings began with the testimony of Calvin McCamy concerning the Zapruder
film, and what a detailed analysis showed about when shots may have been fired. This was
followed by a trajectory analysis presented by Thomas Canning.
The next day of proceedings, and part of the following, was taken by the testimony of
Marina Oswald Porter, former wife of Lee Harvey Oswald. Following that was testimony by
members of the Photographic Panel, who examined the famous "Oswald backyard photos" among
other photographic evidence relevant to the assassination.
The photographic testimony continued into Sept. 15, followed by the testimony of John
Hart. Mr Hart discussed the case of Yuri Nosenko, a Soviet officer who defected to the U.S.
in early 1964. Nosenko's "bona fides" were a subject of great contention within the CIA,
which imprisoned and interrogated Nosenko for a period of three years.
