in 2days episode they showed a hand (of the killer) who was cuttin the rope n the hand was girlish so i think that it is mishti
cause it cannot b simon as she was shown standin down with all the other ppl n anithaaaaaaaaaaaa does not have brains 2 make such a gr8 plan
so killer identified it is mishti!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
this is just my conclusion i don't no this is true or not
