During this robbery, the Insane Killers wear carnival masks, while one wears a dark ski mask. They enter the store, order a cashier to take them to the office, where they obtain the contents of the safe. As they leave the manager obstructs their exit, quite by accident, and is told to lay on the ground. An unsuspecting shopper in the parking lot draws their attention and takes cover under his car dashboard just before the perpetrators drive away. Several bullets hit his car and breaks his window. This is the first supermarket robbery officially linked to the Insane Killers.
