 In 1964, the Warren Commission concluded that each of the three shots that killed JFK were fired from Lee Harvey Oswald's gun. A forensic chemist named Vincent Guinn supported this theory by claiming that Oswald used unique bullets that could be easily identified as coming from the same box. However, scientists in newer studies have discovered that the bullets that shot JFK could have come from numerous guns and from different boxes of bullets. "This finding means that the bullet fragments from the assassination that match could have come from three or more separate bullets," according to researchers from a study at the Annals of Applied Statistics. The researchers add that, "If the assassination fragments are derived from three or more separate bullets, then a second assassin is likely, as the additional bullet would not be attributable to the main suspect, Mr Oswald." Additionally, some witnesses claim to have seen more than three bullets fired. Harvey's rifle, according to a test done by the FBI, could only fire 3 bullets every 8 seconds, making it impossible for him to have shot more than 3 times. Many witnesses also believe that they saw JFK jerk both backward and forward, as it also appears in the Zapruder film, which implies that he was shot from multiple angles. The idea that there might have been more than one gunman opens the door to myriad other possibilities.
