Skinner Co. - Batman: Arkham Unhinged

A meat packing and delivery company based in Gotham City, Skinner Co. was a front for Roman Sionis, aka The Black Mask and his criminal empire. With all the staff in his employ, they ran a tight ship and did not answer kindly to theft and disloyalty; the abattoir and walk on freezers were not only filled with the carcasses of animals. 

While Sionis was running a smuggling operation out of the main factory, Skinner Co were attacked in a sting operation by Tyger Forces. In a devastating ambush, everyone was slaughtered, save for Black Mask himself who was captured whilst trying to escape and taken away to Arkham City at the behest of the super-max's warden, Professor Hugo Strange.
