González was in President Kennedy's fateful motorcade through Dallas on November 22, 1963. He recalled rolling down the window as his car neared the Texas School Book Depository, then hearing three distinct shots during the assassination. González's car proceeded to Parkland Memorial Hospital where, upon seeing a blood-soaked bouquet of roses in the rear of the presidential limousine, he initially believed Jackie Kennedy had been shot. There, he saw Lyndon Johnson, Lady Bird Johnson, Mrs. Kennedy, and President Kennedy's sheet covered body. González helped place Kennedy's casket in the hearse that transported Kennedy to Air Force One.
