Armstrong was featured as a guest artist with Lionel Hampton's band at the famed second Cavalcade of Jazz concert held at Wrigley Field in Los Angeles which was produced by Leon Hefflin Sr. on October 12, 1946.
On 15 October 1946 he was sentenced to death by hanging, with the provision that if he were later found alive, any new facts brought to light at that time could be taken into consideration to reduce the sentence or overturn it.
In October 1946, Luciano secretly moved to Havana, Cuba. Luciano first took a freighter from Naples to Caracas, Venezuela, then flew to Rio de Janeiro, Brazil. He then flew to Mexico City and doubled back to Caracas, where he took a private plane to Camaguey, Cuba, finally arriving on October 29. Luciano was then driven to Havana, where he moved into an estate in the Miramar section of the city. His objective was to be closer to the US so that he could resume control over American Mafia operations and eventually return home.
