What gun was Kennedy assassinated by?

Carcano M9/KOLOC-0//38 manual rifle/KOLOC-0/963/KOLOC-0/2: 30/KOLOC-0/October 22, he was suspected of being from a seven-story building at No.4/KOLOC-0/KOLOC-0/Yushu Street. At that time, President John F. Kennedy and his wife Jacqueline Kennedy arrived at the World Trade Center in a Lincoln limousine, and then drove to Elm Street. Within 8: 5 seconds, gunshots rang three times, and Kennedy was shot, about 80 yards from the sixth floor window of the textbook warehouse. A bullet went through the throat from behind. The president leaned forward in pain and raised his hands to his throat. His wife tried to hold him. Just then, another shot hit his head, which was already a shattered head in front of his wife. Kennedy died after being taken to hospital. A few hours after the incident, detectives found an M C 6.5 mm rifle by the window sill on the sixth floor. An hour later, the CIA arrested him.
