Quinton Bosh appeared in the episode Black Cherry. He was one of the killers of Lemuel McVie.
Victor, Nathan, and Quinton were all in the woods at Carrington during the retreat, including Lemuel, drinking and hunting. Lemuel was not interested in hunting that day. Bosch saw a branch move and thought it was a deer. They started to shoot. They went to see what they had got, and realized it was a man. They panicked and while Lemuel wanted to go to the police, the others disagreed and finally hid the body together. But when they got back from the retreat, Lemuel insisted they should come clean. Dilmer got Lemuel to come to the Catalina 2, under the pretense of meeting late arriving customers. Instead, Dilmer, Fipps and Bosch met him there and beat him to death. They were planning to hide Lemuel’s car, but it was stolen before they had a chance to do so.
