Two barrels for a two timer

Steve Spano was thirty-one years old, lived with his wife, three kids and his mother and was known as a leader of Italian voters. While walking down the street on this date in 1921 Spano was cut down by a blast from a sawed off double barrel shotgun. Two men ran from the building where the shots came from and there police found the weapon.
While searching Spano's affects the police came across a picture of a woman in his pocket watch but it was not Mrs. Spano. When confronted with the photo Mrs. Spano, who said she was unaware that her husband carried around another woman's picture, said, "There was no other woman. No, no. Steve was a good man. We were married fifteen years. We were happy oh, so happy."
