Kansas City asks Oklahoma City for a slug and shell reportedly fired from the gun of "Pretty Boy" Floyd in a bank robbery, "so that they might be compared by the ballistic expert, here, with shells and slugs on hand here."

Part 04 of the FBI Vault's Kansas City Massacre file, page 27 of the viewer; Bureau serial 62-28915-120. The letter is captioned "Unknown Subjects, Obstruction of Justice (Endeavor to Deliver Federal Prisoner Frank Nash)." Acting Special Agent in Charge M. C. Spear reports that "Mr. Gill, ballistic expert," understood the Oklahoma State Bureau of Identification held shells and slugs reportedly fired from the gun of "Pretty Boy" Floyd in a bank robbery, and asks for a slug and shell "so that they might be compared by the ballistic expert, here, with shells and slugs on hand here."

This is a request, not a result. The expert's first name is not given, and the outcome of the comparison was not found in the Vault pages searched for this archive.
