An autopsy report on January 18 has revealed Sunanda Pushkar died a "sudden unnatural death" and her body bore several injury marks, deepening the mystery surrounding the death of Union minister Shashi Tharoor's wife, against the backdrop of an alleged marital discord.
 
Pushkar, 52, was found dead in a hotel in South Delhi on Friday, a day after her Twitter spat with a Pakistani journalist Mehr Tarar over an alleged affair with Tharoor. However, Pushkar and Tharoor had issued a joint statement declaring they were happily married.
 
A team of three doctors at the All India Institute of Medical Sciences conducted a videographed post-mortem on the body in the presence of a magistrate. Later, Dr Sudhir Gupta, the head of the panel and AIIMS' forensic sciences department chief, said it was a case of "sudden, unnatural death".
 
Asked if poisoning had not been ruled out as a cause of the death, Dr Adarsh Kumar, additional professor of forensic medicines and one of the members of the panel, said: "Of course", indicating poisoning had not been ruled out.
 
"If a person is suffering from a disease, the terminal event may be something else. It doesn't matter. Let the investigation be over."
 
A team of doctors, who analysed the results of a series of tests she underwent, said the results did not show that she suffered from any serious illnesses.
 
"We cannot find that she had been suffering from any serious health problems....Like any other person these days, she had come for a complete check up...She had been given only simple medicines," eminent cardiologist Dr G Vijayaraghavan, who headed the team of doctors, told reporters after a meeting of the medical board at KIMS here.
 
Investigators said they are screening the call details record of Pushkar as well as her tweets in the last few days. Her ipad and iphone have also been collected by the investigators to ascertain who she was in touch with before her death.
 
They said a number of hotel staff, including those who had gone to the suite, were being questioned to corroborate the version of Tharooor and his staff.
