He did not complete his investigation, however, because he was told to stop, and to hand the rifle over to FBI Agent Vince Drain, because the FBI would finish the investigation. He later did his own research, however, and concluded that the prints were Oswald's, because by then he had Oswald's prints on file. Police Chief Jesse Curry testified that—despite believing that the FBI had no jurisdiction over the case—he complied with FBI requests to send the rifle and all other evidence to their laboratories in Washington. During the night after Kennedy's murder, the rifle was taken by FBI agent Vincent Drain from Dallas to Washington D.C., who then gave it to FBI agent Robert Frazier. He testified that he kept it in the FBI office until November 27, 1963, whereupon it was sent back to Dallas and given back to someone at the Dallas Police Department for reasons unclear. It was later sent back to the FBI headquarters in Washington. Sebastian Latona, supervisor of the Latent Fingerprint section of the FBI's Identification Division, testified that the palm print found on the barrel of the rifle belonged to Lee Harvey Oswald. Experts agree that palm prints are as unique as fingerprints for the purpose of establishing identification. Initially misidentified as being a German-made Mauser rifle, the Dallas police, upon examination in their lab, determined it to be an Italian-made Carcano. The Warren Commission concluded that the initial identification of the rifle as a Mauser was in error. The House Select Committee on Assassinations investigated claims from researchers that the rifle in fact was a Mauser. The Committee compared photos taken by the Dallas police of the rifle in place, a news film of the rifle being recovered, news photos of the rifle being carried from the Depository, numerous news photos and films of the rifle being carried through the halls of the Dallas police headquarters, as well as photos later taken by the FBI and the Dallas police, and compared them to the Carcano rifle held at the National Archives. They concluded the rifle depicted in the photos and films was the same rifle held in the Archives and therefore was the Carcano and not a Mauser. This surplus-sold rifle had the markings: "CAL. 6.5", "MADE ITALY", and "Terni", (the city of the manufacturer: the Royal Arms factory, "Regia fabbrica d'armi di Terni") stamped with the Italian royal crown as part of the Terni factory symbol, and "ROCCA" (the manufacturer of the bolt cocking piece); it also had the serial number C 2766 and the numerals "1940" and "40" (the year of manufacture).
