Starting to think that BCK and BLK were in on it together in some fashion.

I also think there's a possibility they were both trying to frame each other. Hence the sheath left at the scene with BCK's DNA.



Two things I have been absolutely certain of from day one is that no shot the two roommates slept through it and no chance only one guy did this alone.



Also, I just cannot wrap my head around the fact that none of them tried to call for help during all of this. Even one of the victims. Really makes me think it had to be more than one person.
