A gunshot in Dealey Plaza was reported to the Dallas Police approximately one week before the assassination. Mrs. Joe Baily Blackwell, of Dallas, and her sister were approaching the Triple Underpass when they were shot at and a bullet lodged in their car. The police were unable to determine the source of the shot.
The HSCA investigated bullet fragments that were unavailable to the Warren Commission. In 1974, near the triple overpass in Dealey Plaza, Richard Lester found a bullet fragment. The FBI determined that the Lester bullet fragment was of a 6.5 millimeter caliber but was not "jacketed, softpoint or jacketed, hollow-point sporting bullet, whereas the Mannlicher-Carcano bullet was to be a full metal-jacketed, military-type." The laboratory concluded that the bullet had not been fired from Oswald's Mannlicher Carcano. The second item of evidence was a bullet found in 1967 on top of the Massey Roofing Co. building by Richard Haythorne. The HSCA investigation found that the jacketed, soft-point .30 calibre bullet was consistent with Remington-Peters ammunition. The bullet was not fired from the Mannlicher-Carcano.
In 1975 a maintenance worker on the roof of the Dallas County Records Building, located diagonally from the Texas School Book Depository, found a 30.06 shell under a lip of roofing tar at the base of the roof's parapet on the side facing Dealey Plaza. The shell casing was dated 1953. The condition of the shell indicated it had been on the roof for a long period of time. The HSCA made no mention of this shell.
