After waiting till 12 in the noon, the house owner opened the door with her set of keys, and found the body. “It was a horrible scene. She was lying down on the floor, and there was blood all over the place,” she said.

The body bore multiple injuries on the neck and head, police said. A knife, the weapon used for committing the murder, was recovered from the spot.
