15 Suspects For the Killer on Scream Queens Season 2

Why she might be the killer:

• Of all the characters, she has the strongest motive to wreck havoc on the hospital. We don't yet know how the rest of Halloween '85 plays out, but I can guarantee she won't be happy about her husband's disappearance.

Why she might not be the killer:

• Why would she wait 31 years to carry our her plan? And why would she wait until the hospital is under new management? It doesn't quite add up.
