Jay Richardson, who performs tribute shows as "The Big Bopper Jr.," hopes an examination of his father's remains will settle rumors a gun might have been fired on board the plane, and tell whether the Big Bopper might have survived the crash impact and died trying to go for help.

In its accident report, the Civil Aeronautics Board said pilot error was the cause of the crash. The report didn't mention a gun belonging to Holly that was found by a farmer two months after the crash.

Newspaper accounts of the gun discovery fueled rumors among fans that the pilot was somehow shot, causing the crash. The owner of the flying service added to the conspiracy theory by insisting his pilot was not at fault, saying the pilot must have been "incapacitated."

No one has ever proved a gun was fired during the flight.
