Who's the Scream Queens Killer? The Latest Theories

Why she might be the killer:

• Well, she's evil, that's for sure. She most likely orchestrated the former sorority president's acid-burning accident and probably knew what she was doing with Ms. Bean.
• We also now know that Chad was dating her other sorority sisters, like Sonya (aka Chanel #2) — who's now dead, and that he slept with others the red devil has attacked. Jealousy may be the motive.

Why she might not be the killer:

• Words seem to be Chanel's weapon of choice, not murder. Plus, she's been attacked by the killer.
• Chanel took Chad's threat and gave Hester a makeover rather than kill her. That proves she's selfish, but maybe not a murderer.
