The House of Representatives Select Committee on Assassinations concluded that Oswald was probably part of a conspiracy that could have included a second gunman who fired but missed Kennedy.
The panel's supporting evidence was a bullet analysis that said fragments collected from the site were too similar to be from more than two slugs.
But the latest report found that many bullets from the same batch used by Oswald had a similar composition.
"Further, we found that one of the thirty bullets analyzed in our study also compositionally matched one of the fragments from the assassination," the article said.
"This finding means that the bullet fragments from the assassination that match could have come from three or more separate bullets."
