Most of these are brutal murders by someone disguised as the Red Devil and Green Meanie in seasons 1 and 2, respectively. The four to wear the Devil costume, whether they killed or not, are either Getrude "GiGi" Caldwell/Jess Meyer, Boone Clemens, Hester "Chanel #6" Ulrich, and Peter "Pete" Martinez.

- For some murders, the killer is unknown. The instances are below:
- Tiffany DeSalle's death: Boone would be responsible for this, but the episodes "Hell Week" and "Mommie Dearest" proved that GiGi was more than the planner, and might have also worn the killer costume. GiGi was absent since the introduction of the new pledges at Kappa Kappa Tau, when this happened.
- Boone Clemens's death: Pete confessed to killing Boone, but the theory that this was done by another is being hinted at. An episode after Boone's death, GiGi implies that Hester was the killer, quoting, "I'm sorry we had to murder your brother". In two episodes, GiGi talks to the Red Devil (Hester), telling her to kill Boone. After Boone's death, the Red Devil has a look of guilt on his face after stabbing Boone.
The main antagonistic figure of Season 1 is the Red Devil.
- It is a costume used in the Red Devil Conspiracy. Four people dressed up as the Devil and murdered people on campus.
- Each killer is agressive, but in different ways:
- Boone was "out of hand" and killed everyone he possibly could.
- Hester only killed when neccessary. She killed Pete because he was about to reveal her as the killer, Mandy because she shedded light on the 1995 KKT incident and unknowingly revealed that the killer is a girl, Zak so she could frame Melanie Dorkus, GiGi because she made her (debatable) kill Boone, and every other murder she committed was simply for her own enjoyment.
- Hester confessed to orchestrating to murders on campus in Season 1.
- In Season 2, Hester is not the killer, but is working with the Green Meanie and is possibly the mind behind his moves. She is said by the producers to be "intimately involved' with the killer, who is her "special friend".
- Chad Radwell's killer is not the Green Meanie, as revealed in "Halloween Blues".
- The killer was not wearing a costume, as Chad saw the face of the person who killed him, as revealed in said episode.
- In the latest episode, coming November 1, Zayday and Libby "Chanel #5" Putney will talk to Jane, a possible antagonist of Season 2, about the killings of 1986, on Halloween night.
