Sheela, 70, resident of west Delhi's Moti Nagar, was found stabbed to death in her house. She was stabbed twice and body was detected by her son Vinod.

"The initial inquiry suggests that the killer was known to the woman and robbery was not the motive as the victim's jewellery and other valuables were found intact. No concrete clue is found yet which can clarify the identity of the culprit," said Deputy Commissioner of Police V. Renganathan.
