Example Input: Question: On what date was the person who sent an emissary rather than attend the 1931 meeting with Luciano and three others in person born? Passage:In April 1931, Salvatore Maranzano, head of the Castellammarese clan in New York City, declared himself capo di tutti capo (boss of all bosses). Lucky Luciano, who opposed Maranzano's claim to control the Luciano crime family, decided to have Maranzano murdered. On April 21, 1931, he met in Cleveland with Frank Milano, Moe Dalitz, Meyer Lansky, Santo Trafficante Sr., and an emissary sent by Al Capone. The five agreed with Luciano's plan to kill Maranzano and establish a new federation of crime families to handle disputes. After the September 10, 1931, assassination of Maranzano, the title of capo di tutti capo was retired and "The Commission" established by the American Mafia. Milano was named a member of The Commission, alongside Joseph Bonanno, Al Capone, Tommy Gagliano, Lucky Luciano, Vincent Mangano, and Joe Profaci.
