New Delhi, March 17 :    New Delhi, March 17:  Natasha Singh, estranged daughter-in-law of Congress leader K. Natwar Singh, was found dead on the first-floor terrace of Delhi's five-star Hyatt Regency Hotel early this morning. The 31-year-old model-turned photographer and mother of two young boys had left her Greater Kailash terrace-home, where she has been living alone, at 11.30 last night for a party. Her body, found around 6.30 this morning, showed no bullet marks or stab wounds in the post-mortem. 'The post-mortem reveals that several of her ribs and other bones were broken, apparently in a fall,' a senior officer said. An SMS message, believed to have been sent from Natasha's mobile phone (9810099411) to her friends last night, said: 'I am going to another world.' Although the message might suggest Natasha was preparing to commit suicide, the police have registered a murder case and have spoken to her husband, Jagat Singh, a Young Congress general secretary. The deputy commissioner of police (southwest), Taj Hassan, said: 'We sought some verification of facts from him over phone.' Hassan said the post-mortem revealed that 'some alcohol was present in her body'. On the seventh floor of the hotel, a bottle of whisky was found with nearly 200 millilitres already drunk, possibly by Natasha, Hassan said. She was last seen at 0035 hours in the hotel lobby. A distress SMS message was sent to Jagat also. Jagat dismissed suggestions of his involvement in the suspected murder as disgusting, saying that Natasha was the mother of his children and he very much loved her. Natasha, born of a Jordanian father and Indian mother, and Jagat married in 1993 and have two children aged five and six. They have been living separately for at least a year and have filed for divorce. Lawyer and Rajya Sabha MP R.K. Anand, who represents Jagat in the divorce case, said the two sides were trying to settle the dispute over custody of their children out of court. The incident came to light when the police followed up a complaint lodged by Natasha's counsel Sushmita Deb at the Greater Kailash police station in south Delhi that Natasha had gone missing since midnight last night after a party. Deb said she went to Natasha's residence on hearing about the SMS message but did not find her there. 'I first called the police station from Natasha's residential phone and later made a written complaint,' she said. Malvika Raj Kothari, also a counsel for the deceased, said Natasha and Jagat had a 'very tempestuous kind of relationship' but the last time 'I met her... She (Natasha) did say that Jagat seemed to be sort of softer and gentler'. 'I asked whether she had planned to patch up things and she said 'I don't think I could go back',' Kothari said.
