Jazzman, a.k.a Jimmy Peake, is a gangster in Gotham City.
Jimmy Peake was a gangster in Gotham City involved in an illegal smuggling operation six years ago. When Lieutenant James Gordon busted Peake, Peake swore revenge upon being delivered to the authorities.
Six years later, Peake, ow Jazzman, initiated a drug sale and lured the Police Departmente to a trap. When Gordon was set to get Jazzman, he was severely wounded and taken to the hospital. Due to prison overcrowding, Judge Maria Vargas sentenced Jazzman to Stonegate Penitentiary to await trial. However, Jazzman escaped and instead of fleeing, he went straight to Gotham Hospital to finish off Gordon. Fortunately, Batman intervened and Jazzman was arrested.
