Well.. shit.. =/
Fare thee well friend, Psychos got their first kill.
We'd be able to tell if the Wendigo did it right, @Pengu? Last time there was a conspicuous ripping in half-ness.

Yes and no.
The characters may be used in the story (not by name), but the kills themselves may or may not reflect entirely the person who chose them.
For instance, this particular kill has a few possibilities:
1) The psychos and Wendigo targeted the same person.
2) At least one target was defended.
3) One kill was purposely not sent in.
4) One of the two teams didn't submit a kill (Keep in mind, I didn't implicate either team in this kill).
So while some have been intentional (the two blatant Wendigo kills, North's murder), others have been left up to question (this kill, Sarah's kill, etc...)
But as far as who committed this one goes...that'll be a mystery until the very end. It could have been the psychos, it could have been a setup by the Wendigo, or it could have been them working together. That's up to you to guess.
