Historic documents about Lee Harvey Oswald that were lost for decades were found, and now sit in the Sixth Floor Museum at Dealey Plaza in Dallas.
Dallas County Medical Examiner Dr. Jeffrey Bernard found a file that includes an order signed by Oswald's widow to exhume his body in 1981.
At the time, there was a conspiracy theory that the President John F. Kennedy assassin was a Russian agent who had assumed Oswald's identity.
A wealthy British lawyer paid a fortune to have the body dug up and re-examined.
"Marina Oswald, the widow, wanted the questions resolved. Not because she had any doubts - because she knew that the questions would keep coming and coming," Gary Mack, Sixth Floor Museum, said. "And she thought the exhumation would put an end to it once and for all."
The Sixth Floor Museum says eventually, the documents will be accessible to the public in its reading room.
