Nupur Talwar (L), mother and alleged murderer, of Indian girl Aarushi is escorted from the Dasna Jail to Ghaziabad Court around 40kms from New Delhi on May 11, 2012. A murder case that has obsessed India for four years has come to court when a middle-class couple from Delhi stand trial on charges of killing their teenage daughter and domestic servant. At first police blamed the servant for murdering Aarushi Talwar, 13, but now her parents are accused of stabbing them both to death in a case awash with sexual rumour, as well as charges of police incompetence and a media witch hunt.
