Jewish Mob
From Grand Theft Wiki
The Jewish Mob is a criminal organization which appeared in Grand Theft Auto IV. The scale of this mob and its general operations is unknown, but its members show up in two missions involving a diamond purchase gone wrong. Isaac Roth, a Hasidic Jew, appears to be the boss of the operation, with Mori Green, a mainstream Orthodox Jew, as his right hand.
The LCPD database says that Roth, Green and The Jewish Mob in general make frequent deals with African warlord Claude Wome, a dealer in conflict diamonds.
Green is killed by Luis Fernando Lopez at the failed deal at the Libertonian Museum in Museum Piece. Roth is killed at the Majestic Hotel by Niko Bellic, under orders of Ray Boccino, in the mission Late Checkout.
