The possibility that accomplices aided Oswald in connection with his escape was suggested by the testimony of Earlene Roberts, the housekeeper at the 1026 North Beckley roominghouse.[C6-88] She testified that at about 1 p.m. on November 22, after Oswald had returned to the roominghouse, a Dallas police car drove slowly by the front of the 1026 North Beckley premises and stopped momentarily; she said she heard its horn several times.[C6-89] Mrs. Roberts stated that the occupants of the car were not known to her even though she had worked for some policemen who would occasionally come by.[C6-90] She said the policeman she knew drove car No. 170 and that this was not the number on the police car that honked on November 22. She testified that she first thought the car she saw was No. 106 and then said that it was No. 107.[C6-91] In an FBI interview she had stated that she looked out the front window and saw police car No. 207.[C6-92] Investigation has not produced any evidence that there was a police vehicle in the area of 1026 North Beckley at about 1 p.m. on November 22.[C6-93] Squad car 207 was at the Texas School Book Depository Building, as was car 106. Squad cars 170 and 107 were sold in April 1963 and their numbers were not reassigned until February 1964.[C6-94] Whatever may be the accuracy of Mrs. Roberts’ recollection concerning the police car, it is apparent from Mrs. Roberts’ further testimony that she did not see Oswald enter a car when he hurriedly left the house. She has stated that when she last saw Oswald, shortly after 1 p.m., he was standing at a bus stop in front of the house.[C6-95] Oswald was next seen less than 1 mile away, at the point where he shot Patrolman Tippit. Oswald could have easily reached this point on foot by about 1:16 p.m., when Tippit was shot. Finally, investigation has produced no evidence that Oswald had prearranged plans for a means to leave Dallas after the assassination or that any other person was to have provided him assistance in hiding or in departing the city.
