LUCKNOW, May 25 -- A 14-year-old boy, who allegedly murdered his 70-year-old grandmother, Vidya, over a demand for Rs.500, spent the entire night sleeping beside her corpse to avoid suspicion, said police officials investigating the case.

"He spent the entire night beside his grandmother's lifeless body, pretending nothing had happened," said a police officer.

The next morning, the boy locked the door using a brick and told a neighbour that his grandmother was unwell and that he was heading to school. Hours later, suspicious neighbours forced their way into the house and discovered Vidya's body lying on the bed. The police were called immediately.

The incident took place on the intervening night of May 21 and 22 in Muzasa village, Mali...
