Rajesh and Nupur Talwar were convicted of double murder of Aarushi Talwar and their domestic help, Hemraj Banjade in 2008. They got life sentences on Nov 23th, 2013. This case is so botched up that the claims made by CBI and prosecution claims do not make sense. Referring back to the infamous case of O.J. Simpson, common people could then understand that the suspect had a motive - that is, a disgruntled husband finding her wife having an affair with another man.
In the case of Aarush murder case, the initial claim made by CBI was that the father caught her 14 yrs old daughter in a compromising position with an older man and so in the fit of anger, they killed both of them. This is such a bizarre and far-fetched motive. Unless the man is a psycho or a serial-killer, no biological parent can possibly kill his/her own daughter even if she is caught in a compromising situation. However, some say that there were only 4 people (The Talways, Aarushi and Hemraj were there in the apartment) and honor-killings are prevalent in North India.
Then there were numerous inconclusive evidences. Even at one point in time, CBI decided to close the case. However, Rajesh and Nupur Talwar didn't want the case to be closed. Some people will say it was their mistake (in retrospect) but one can also say that they didn't want their names to be floating around as possible murder suspects (like OJ Simpson). It also suggests that probably they wanted to find the real culprit. Can someone fake so much intent or motive ?
I would rather let the real culprit/suspect roam freely but I would not let an innocent be convicted. I am not saying Rajesh and Nupur Talwar are innocent that but until unless one is not 100% sure, the benefit of doubt should be given to the accused, specially in a case where the investigation is botched up and it's a murder trial.
