Mirrow, surveilance tape and stab wounds
Something doesn't add up here. I have three questions:
1) How did they tamper with the surveilance tapes?
2) How was the chinese girl able to look through the two way mirror?
3) How where they able to make such percise stabwounds on every victim, which the coroner said would require surgical capability?
They were just kids unhappy with their lives, but how was the above possible? Nothing about the ending suggested anything even remotely supernatural.
