November 4 – Mob financier Arnold Rothstein is shot by an unidentified gunman while at Manhattan's Park-Central Hotel and dies of his wounds at the Polyclinic Hospital the following day. Rothstein's murder would be attributed to his refusal to pay a $320,000 gambling debt from a three-day poker. Rothstein had refused to pay because he said the game was dishonest. George "Hump" McManus, a participant in the game, would be arrested for Rothstein's murder, but later acquitted due to lack of evidence.
