Who knows about Om’s real killers?

I am confused, i know that Parvati and Narayani know for certain, that Trishna/Rajo are the killers of Om and also Krishna's

And i presume Suyash knows, one thing that puzzles me is why is he still with Rajo knowing that she killed Om, no wonder Parvati thinks he's connected

Also does Kamal know now? and also Gunn, coz didnt she take on the case of Parvati?

^^Om doesn't look like a guy who would get into greed for money..i don't think that's why he married Trishna. He married her because her mental health was not good or something around that. Trishna mentions something like that when she admits to Parvati that she killed Om. Anyways,Krishna would have been shot by Rajeshwari or Trishna. Thing is, though, the way Parvati was sent to jail was too stupid. First of all, just because your fingerprints are on a gun doesnj't necessarily mean you're the wrong-doer. Secondly, the whole "mobile phone in Parvati's name" also doesn't necessarily mean that the phone belonged to her. The police didn't do much to try and find the real killer, so whatever to that. We definately know Rajeshwari and Trishna are behind everything from their convo in the last episode and everything else.
