Who is the culprit for Kangana’s death

As everyone know the show ended so abruptly. So let us make guesses who the culprit for K's death are.

I think in a way Priyam & Abhay.

When K dropped the medicine a girl put in a chit. It could be Priyam's plan. He followed her and made the girl put in the slip in her bag. K read that and frustrated she must have gone out and Abhay kidnapped her. And rest we know.
