"In late September, 1963...Lee Harvey Oswald left New Orleans and made a bus trip to Mexico City. His purpose was ostensibly to try to get visas in Mexico City to go to Cuba and Russia. Oswald boarded a Flecha Roja (Red Arrow) bus for Mexico City. Boarding this same bus was a man identified by his tourist card as John Howard Bowen. According to witnesses, he sat next to Oswald on the long overnight Flecha Roja bus ride to Mexico City...But Bowen's tourist card was full of false information. His real name was Albert Alexander Osborne. Oswald had twice used the alias "Osborne" in New Orleans, soon after working in Dallas with a man named John Grossi who used the alias Jack Bowen...Albert Osborne died, apparently of food poisoning, on August 31, 1966, in San Antonio, Texas. He was 77 years old. Reverend Lyman Erickson of San Antonio, who occasionally provided Osborne a room and helped him in his final days, told the BBC program "Kennedy: The Grimsby Connection" in 2003 that he suspected that Osborne was an intelligence agent."
On 11/22/63, Oswald's wallet contained a Dallas public library card with Oswald's name was on the front and back, and Jack Leslie Bowen was also listed on the card. Bowen was questioned in NYC, and said that he agreed to be a reference so Oswald could obtain Russian books. Both men were working at Jaggars-Chiles-Stovall; Oswald as a camera trainee. He lent his library card to Eddie Reddell of Mohr Chevrolet, who confirmed it in a 12/13/63 interview - see FBI 105-82555 Oswald HQ File, Section 57 - p. 67.
