New research suggests that science cannot support the assertion that Lee Harvey Oswald was the lone assassin of President John F. Kennedy.
Cliff Spiegelman, a professor of statistics at Texas A&M University, said that five bullet fragments taken from JFK’s body could have come from more than the two bullets which are said to have cut down the president in Dallas in November 1963.
“The claim was made that those five fragments could only have come from two bullets,” Spiegelman said. “Our research showed it could have been two or more.
“And if it is more than two, there is an increased likelihood that someone else provided one of them.”
He organized a six-member team that compared the composition of the fragments from the JFK shooting to other bullets from the same manufacturer.
The group found that those fragments weren’t nearly as rare as the government’s expert witness concluded in 1976, when Dr. Vincent P. Guinn determined that all five fragments came from two bullets fired by Lee Harvey Oswald. A third shot missed.
Spiegelman said many of the test bullets showed the same “chemical composition,” and one matched fragments from the assassination bullets.
The study does not say there were two or more gunmen, only that the single-gunman theory can’t be supported by science.
Naturally, that triggered “a bit of a buzz,” said Gary Mack, curator of The Sixth Floor Museum at Dealey Plaza.
“The no-conspiracy folks, they accepted (Dr. Guinn’s) analysis without too much questioning,” Mack said. “But others wondered whether he knew what he was talking about. And the sharp ones were very skeptical that (the one-shooter findings) could be so definitive.”
The team’s research won them the American Statistical Association’s 2008 Statistics in Chemistry award.
