Om Gayatri Prinku Ishaana

Hmm how's this random girl dying related to gayatri...

I think girl that died was Ishaana...
Cus gayatri and roop hired ishaana to spy on oberois

How are all these related...The police could be thinking...few options...

1. Om knew ishaana and killed her. Of course we know it's an accident but they could make it seem like it was planned since om knew her and they got in huge tiff and all.

2.Or Even if it's an accident they still hid it so that's also jail time. Where's the body? Om doesn't have family's alibi for that night cus he wasn't present when shivaay proposed to tia

3. Or Could imply driving while intoxicated on om's part
Why he would be driving when like that? Cus prinku called him somewhere so he had to go to protect his sister and bam accident happens

Now big question is why did prinku call om in panic?
I think gayatri tried to kill Ishaana cus she was not useful and did not want her to expose gayatri so she called her in forest to kill her. Accidentally gayatri gets killed. Ishaana runs away and gets killed by om, accidentally. Prinku happens to be near the murder or hears a shot and calls her big brother..
