Study: JFK lone-gunman evidence 'not a slam dunk'

New testing on the type of ammunition used in the 1963 assassination of President John F. Kennedy raises questions about whether Lee Harvey Oswald acted alone, according to a study by researchers at Texas A&M University.

Lead researcher Cliff Spiegelman stressed, however, that the research doesn't necessarily support conspiracy theorists who for decades have doubted Oswald was the lone gunman.

"We're not saying there was a conspiracy. All we're saying is the evidence that was presented as a slam dunk for a single shooter is not a slam dunk," said Spiegelman, a Texas A&M statistics professor and an expert in bullet-lead analysis.
