_Additional corroborative evidence._--The admissions made to Marina Oswald by her husband are an important element in the evidence that Lee Harvey Oswald fired the shot at General Walker. As shown above, the note and the photographs of Walker’s house and of the nearby railroad tracks provide important corroboration for her account of the incident. Other details described by Marina Oswald coincide with facts developed independently of her statements. She testified that her husband had postponed his attempt to kill Walker until that Wednesday because he had heard that there was to be a gathering at the church next door to Walker’s house on that evening. He indicated that he wanted more people in the vicinity at the time of the attempt so that his arrival and departure would not attract great attention.[C4-737] An official of this church told FBI agents that services are held every Wednesday at the church except during the month of August.[C4-738] Marina Oswald also testified that her husband had used a bus to return home.[C4-739] A study of the bus routes indicates that Oswald could have taken any one of several different buses to Walker’s house or to a point near the railroad tracks where he may have concealed the rifle.[C4-740] It would have been possible for him to take different routes in approaching and leaving the scene of the shooting. _Conclusion._--Based on (1) the contents of the note which Oswald left for his wife on April 10, 1963, (2) the photographs found among Oswald’s possessions, (3) the testimony of firearms identification experts, and (4) the testimony of Marina Oswald, the Commission has concluded that Lee Harvey Oswald attempted to take the life of Maj. Gen. Edwin A. Walker (Resigned, U.S. Army) on April 10, 1963. The finding that Lee Harvey Oswald attempted to murder a public figure in April 1963 was considered of probative value in this investigation, although the Commission’s conclusion concerning the identity of the assassin was based on evidence independent of the finding that Oswald attempted to kill General Walker. Richard M. Nixon Incident Another alleged threat by Oswald against a public figure involved former Vice President Richard M. Nixon. In January 1964, Marina Oswald and her business manager, James Martin, told Robert Oswald, Lee Harvey Oswald’s brother, that Oswald had once threatened to shoot former Vice President Richard M. Nixon.[C4-741] When Marina Oswald testified before the Commission on February 3-6, 1964, she had failed to mention the incident when she was asked whether Oswald had ever expressed any hostility toward any official of the United States.[C4-742] The Commission first learned of this incident when Robert Oswald related it to FBI agents on February 19, 1964,[C4-743] and to the Commission on February 21.[C4-744]
