Mick O'Shea is the brother of Tim O'Shea and a gang leader, who runs the docks in Toronto. He assaults Brackenreid with his brother to emphasize the point that he shouldn't mess with them. At least three months later, he and his brother are suspects in murders similar to the way Brackenreid was beaten. He and his brother were later killed by their employer in an attempt to frame Brackenreid and make it look like he had killed them in retaliation for their assault on him.
