TNN, New Delhi : The forensic report of Sunanda Pushkar has revealed that her death was caused by drug poisoning. Doctors say that this means that Sunanda did not die because of an inadvertent drug overdose but by deliberate administration of drugs aimed to end life. Whether this was suicidal or homicidal, the doctors are unable to say, adding that was for the police to establish. Sources at the All India Institute of Medical Sciences (AIIMS), where the post-mortem was conducted on Saturday, said the forensic findings have been submitted in a sealed envelope to the sub-divisional magistrate (SDM) who is holding the inquest proceedings under the provisions of the Criminal Procedural Code. The forensic report gives a new turn to the investigations into the death. Police officials said the report will now require them to review all the video footages of the hotel lobby and check who all went to her room, including the hotel staff. Alok Sharma, the SDM who is holding the inquest proceedings, refused to disclose the details of the report. He said he would examine it along with the statements of various people, including that of Tharoor and Sunanda’s brother as well as other evidence.
