Shinneas is a gangster from North City who makes his way to North Harbor to get revenge on the Saku family. Since Jaboo and Cassie pulverized his boss, he attempts to get his revenge by breaking into their house and catching them by surprise. He is the new leader of his gang, the Silent Snakes, after his leader is gone. Shinneas runs things differently and is much more forceful. He aims for committing as much crime as possible and placing the blame on other rival gangs, so they can stay in the shadows and away from surveillance.
