Zagtun Bonecrusher was a notorious businessman in the 2280s decade. In the year 2287, Bonecrusher hired the bounty hunter Sweeney to track down a former associate of his named Nanoc. Sweeney successfully captured Nanoc, but was unable to receive payment when Bonecrusher was found to have died at Beta Origii. Sweeney offered Nanoc the opportunity to buy his freedom, but he didn't have any money, so Sweeney killed him anyway. (TOS comic: "Not... Sweeney!")
