LUCKNOW, May 19 -- An adolescent girl allegedly killed her mother with the help of a male friend, also a minor, in the woman's house in Chinhat here in the wee hours of Sunday. Not only did the two slit her throat, but they also tried to stage the crime scene, police said. The police found her statement inconsistent and questioned her further. Later, she confessed to the murder of her mother, Usha Singh, 40. Deputy commissioner of police (East) Shashank Singh said Usha's daughter, a minor, was romantically involved with the boy, who spent some time at a juvenile home for trying to elope with the girl last year. "On the night of the incident, he came to the house and, with the girl's help, tried to strangle Usha. They, then, slit Usha's throat with a glass shard," he said. The police said the duo tried to make it appear that the woman was raped and murdered. Her body had been sent for post-mortem, they said.HTC...
