This double-murder is slowly gaining the mysterious aura of Jack the Ripper and other unsolved criminal cases. Who on earth committed these murders? Anyone who is picked up by the police or CBI very calmly accepts his involvement in the crime. What appeared to be a open-and-shut-case has hit the dead end. I think there is going to be no headway in the case. There is a crying need for having two separate streams of policing i.e. law and order; and investigation and prosecution. Otherwise the police will continue to goof up on investigations.
