Because its a matter of honor...Its a big deal to most Indians...
I have known of women in central India where I was born, where women were accused of adultery by their husbands or in laws, and resorted to taking their own lives rather than having to live with the shame of being labeled an adulterer or "Chenal/Kulta"...
Some may have been guilty, others not...But its inconclusive as is this case..
Its like being accused of being a pedophile or a rapist if you arent one...and even if the courts dismiss the case and give you a clean chit, society still looks at you suspiciously and its a matter of dishonor of massive proportions to be labelled one..
Think of this as "Seppuku" seen in Japanese culture..
Police question different people during the criminal investigation, not everyone being question implication of the crime. Since the police didn't charge him with the crime, no one will find out if he maybe a suspect or not but his dead surely related to this criminal case. Majority people will err on the side he probably primary suspect but the police still not complete their investigation to charge him with the crime.

In that case please do share and we can find closure. 
That's the alpha beta of it all. Thanks.
