At Zapruder frame 313 Tague's head top was located 271 feet away from and 16.4 feet below President Kennedy's head top and the limousine's front windshield and its pushed nearly vertically straight-upwards sun visors were in between the president and the impacted curb point. The bullet or bullet fragment that struck the concrete curb was never found. The Warren Commission report states that seconds after the shooting Roy Kellerman consulted his watch and said "12:30" to William Greer, before he radioed to Police Chief Jesse Curry that the President had been shot. Curry then communicated an order for Parkland Hospital to stand by - the Dallas police radio log reflects that this communication was made at 12:30. Immediate aftermath Lee Harvey Oswald Oswald was confronted by Dallas patrolman Marion L. Baker and Texas School Book Depository superintendent Roy Truly in the second-floor lunchroom. Baker let Oswald pass after Truly identified Oswald as an employee. Oswald was next seen by a secretary as he crossed through the second-floor business office carrying a soda bottle. He left the building through its front door at approximately 12:33 p.m. Initially, Truly and Occhus Campbell, the Texas School Book Depository's vice president, said that they had seen Oswald in the first-floor storage room. When asked during his interrogations about his whereabouts, Oswald claimed that he "went outside to watch P. Parade"(referring to the presidential motorcade), was "out with [William Shelley, a foreman at the depository] in front" and that he was at the "front entrance to the first floor" when he encountered a policeman. Estimates of when the depository building was sealed off by police range from 12:33 to 12:50 p.m. The streets in and around Dealey Plaza were not immediately closed, and photographs taken just nine minutes after the assassination show that vehicles were still driving on Elm Street in front of the Texas School Book Depository. After leaving the depository, Oswald walked seven blocks before boarding a bus. When the bus became ensnarled in traffic, he exited the bus, walked to a nearby bus station, and hired a taxi. He asked the cab driver to stop several blocks past his rooming house at 1026 North Beckley Ave., and he then walked back to the house. He arrived there at around 1:00 p.m. According to housekeeper Earlene Roberts, he departed three or four minutes later. She last saw him standing at a bus stop
