Jack Welker

John "Jack" Welker, known as Uncle Jack, is the leader of a criminal gang with white supremacist or neo-Nazi ideologies in Breaking Bad, played by Michael Bowen. His nephew Todd Alquist belongs to the gang, which is heavily armed with military-grade weaponry and works as assassins for hire, its jailed members killing targets inside prisons. He became an enforcer in Walter White's drug empire, which Walt drew him into by offering to pay to have ten prison inmates murdered across three facilities within a two-minute window, and he died on September 7, 2010, shot in the head by Walt.
