Avirook Sen, the author of the book based on the 2008 murder of Aarushi Talwar and domestic help Hemraj, welcomed the Allahabad High Court judgement acquitting her parents Rajesh and Nupur Talwar, saying the wrong done by the CBI has been corrected.The couple had been sentenced to life imprisonment by a special Central Bureau of Investigation court in Ghaziabad in 2013. They had appealed in the high court, which on Thursday, acquitted them of the double murder, giving them the benefit of doubt."I am glad that the wrong that was done in Ghaziabad has been corrected. It has been reversed today by the honourable High Court," Sen told IANS, adding "they have spent nearly a decade under this cloud and have finally been acquitted". Of his personal observation of Aarushi's parents, he said: "I remember the couple's life as a life mainly of pressure and sadness."As after the High Court verdict, the double murder remains an unsolved case, Sen feels that the court has played its responsibility and it is the duty of the CBI to find the murderers."It's not the High Court's mandate to investigate and find out who the killers are. The court is charged with only one responsibility and that was on the evidence presented by CBI against the Talwars. They have answered the question that they were asked," he said."To find out the killers is neither the responsibility of the journalists, nor the court... it is the responsibility of the CBI that they should do some reflection and try and understand why we couldn't put their cases properly," he added.
