February 1, 1933. Late that night, John ""The Cropper"" Cropsie, the Enforcer for Jules Flack (boss of the Westside combine), stood in the back alley behind the Lido Burlesque house, by the stagedoor entrance-- and pumped some slugs into David Alpine, the key booze supplier for the combine (because he was also selling to the competition). On the night of February 2, Eliot Ness is having Cropsie reenact the crime in front of an eyewitness to the shooting: Belle Alpine, David Alpine's widow. Ness asks her if she can identify him as the man who shot her husband. Belle walks up to Cropsie, slaps him across the face, and then blatantly lies to Ness that she never saw him before in her life. Meanwhile, with Repeal of Prohibition just around the corner, Jules Flack is getting ready for the big switch, he is going to concentrate on narcotics. Flack wants to convert his assets into a couple of million bucks, so he can throw in with Luciano. Cropsie, who had been Flack's Enforcer for 13 years (thetvdb.com)
