With the CBI unable to gather tangible evidence against the three accused, Krishna, Rajkumar and Vijay Mandal in the Arushi-Hemraj murder case, the filing of the first charge sheet seems to be uncertain. Just last week, one of the accused, Vijay Mondol, got bail and now, with the CBI getting no evidence against them, the families of the two other accussed Krishna and Rajkumar hope to see them walking out free.
