everyone.....is thinking....about the killer but.............
i think that ADITI is the killer bcoz , shez a good photographer n the lady investigator told that the killer used a special chemical used by photographers to kill tanu n she even told ashu that she saw om at the middle of that nite
may b shez sumone like a relative of that vijay,as they told earlier that vijay was her uncle n all , so she may have a motive to destroy the aggarwals thatz why shez doin all thiz
she may b tryin to dislocate the police's eye from her thatz why she is trying to hide herself n blaming other like om n now vandy (as she told ashu)
so whatt do u think guysđ
