Scream Queens: All the Hints We Have About the Killers

There are a few shady characters on Scream Queens, and Boone has been a suspect since the premiere. He fakes his own death, then is released from the morgue by a mysterious partner. The latest episode confirms that he's one of the killers, as he's seen in disguise at the gym. He picks up his phone and is clearly speaking to another killer, complaining: "All I do is work out and kill people." He also says that Gigi is ruining their image with her Supreme Court Justice Antonin Scalia mask and that they need to "take her out, then we finish what we set out to do." Case closed: he's one of the killers.
