On April 30 the group decided to steal clothes at a local Dillard's store for an upcoming "Grad Nite" at Walt Disney World, where Foster planned to steal one of the character's costumes to use as a disguise to shoot minorities at the amusement park. As part of their diversion Foster rigged a smoke grenade, which he had purchased at an Army-Navy store, with fishing wire. The plan was to stack up the clothes they wanted and run out when the grenade went off. The grenade proved to be a dud.
