MUMBAI: When a woman with blood-stained hands entered Manickpur police station on Sunday morning and admitted to killing her daughter-in-law, even beat-hardened cops were left wide-eyed.Vasai resident Anandi Mane (48), told the police that she had bludgeoned her daughter-in-law, Riya alias Swati Mane (33), to death with a metal vase when she was fast asleep as she blamed her for ‘taking her son away’ to the US after marriage. Anandi also disliked Riya’s nursing profession and even her name, forcing her to change both, said sources.She has been booked for murder and admitted to the civic-run D M Petit Hospital as she had consumed several sleeping pills the previous night. Police are verifying if Anandi had taken the pills in an attempt to commit suicide.The police went to the Manes’ flat in Om Nagar, Vasai (W), and found Riya’s body in the bedroom, the blood-stained vase on the pillow and her six-month-old daughter fast asleep on the bed. Riya’s husband Rohan (33) and father-in-law Dattatray had gone for their morning walk. Anandi’s youngest son and daughter-in-law were in their bedroom and unaware about the happenings till the police arrived.Riya and Rohan had a love marriage five years ago. Rohan, an engineer, moved to the US soon after marriage as she had landed a nurse’s job in Houston , Texas . The couple had flown down from US on December 1 for a vacation. Last weekend, the couple, along with the family, had even attended a relative’s wedding.Anandi, in her police statement, said Riya did not allow her to spend time with her granddaughter. On Saturday, when Anandi was getting ready to take her granddaughter for a walk, Riya refused.

She then reached the police station. Riya’s body has been sent for autopsy.
