Here is one way to eliminate.

Eliminate Scott's pack:

Scott McCall (alpha) Stiles Stilinski (human) Lydia Martin (banshee) Malia Tate (werecoyote) Kira Yukimura (kitsune) Liam Dunbar (beta) Derek Hale (beta)

Now eliminate parents of Scott's pack members, because it doesn't make sense for a loving parent to put his/her own child in danger:

Melissa McCall (mother of Scott) Rafael McCall (father of Scott) Sheriff Stilinski (father of Stiles) Ken Yukimura (father of Kira) Noshiko Yukimura (kitsune)

Remaining candidates:

Alan Deaton (veterinarian) Araya Calavera (werewolf hunter) Bobby Finstock (lacrosse coach) Braeden (mercenary) Brett Talbot (beta) Chris Argent (werewolf hunter) Deputy Haigh (sheriff's deputy) Jordan Parrish (sheriff's deputy) Kate Argent (werejaguar) Mason (friend of Liam) Ms. Fleming (math teacher) Natalie Martin (mother of Lydia) Peter Hale (beta) Severo (Araya's right-hand man)
