A palm-sized cd has become the prized possession of Jagdish Mehta, the father of social activist Lalit Mehta, who was brutally murdered in Kandra jungles of Palamu district in Jharkhand on May 14. His eyes gleam as he holds the cd in his hands. It contains a record of a damning social audit of an nregs project in Chhatarpur block, and the old man hopes it may one day nail the culprits.
