New Delhi: The police may send the viscera samples of Congress leader Shashi Tharoor's wife Sunanda Pushkar to forensic laboratories abroad to determine the type of poison that is suspected to have caused her death, as per reports on Thursday.
The viscera samples may be send to a UK-based laboratory which has facilities to test all kinds of poisons.
"With this almost clear that Sunanda died of poisoning, the biggest question which remains in the case is that the kind of poison (used) and how it reached her body. If these question can be answered, the case could head to its logical end," the official said on condition of anonymity, as per PTI.
As of now, the police have asked the AIIMS panel of doctors to redo their investigation and name the poison which caused Sunanda's death but if it fails to do so, the samples will then be sent abroad.
The police today questioned some people who were related to the case but senior officials refused to divulge the identities of these people and what they told police
On October 19, 2014, it was reported that poison had been found in the final viscera report of Pushkar.
The viscera report had been submitted by AIIMS doctors to Delhi Police on September 30 called the 'Subsequent Medical Board Opinion'.
The new report by the panel of doctors, who had conducted the autopsy on her, was prepared on the basis of the findings of the Central Forensic Science Laboratory (CFSL) which had examined Sunanda's viscera, sources had said.
They said that the team had again concluded like it did in its first report that her kidney, liver and heart were functioning normally and that her death was caused by poisoning.
The AIIMS panel of doctors had earlier said the police had not shared with it the photographs of scene of occurrence, statements and circumstantial evidences with them.
Police had not quizzed a single person in the last nine months nor did it try to inspect the 'crime' scene.
It was only after the AIIMS report that the police got suite number 345 of Leela Palace Hotel, where Pushkar was found dead, opened.
Police had also called upon the AIIMS doctors and experts from FSL to inspect the room during which fluid marks were found on Sunanda's bed sheet, the carpet and a broken glass in the room. These articles have also been sent to forensic labs for examination.
The suite of the five star hotel, had remained sealed and was opened for the first time since the incident.
Police had also got information regarding Pushkar's twin email accounts from Yahoo and Google with details of whom she was in touch during her last days.
A list of these people through their IP addresses was made by the police and they were quizzed about the conversations.
Their statements are now being tallied with each other and also with those which were recorded before the SDM during the initial investigation.
Meanwhile, as per reports yesterday, the Delhi Police have sent Pushkar's three mobile phones and a laptop for forensic examination at CFSL, Gandhinagar in Gujarat.
Sunanda was found dead at a five-star hotel in South Delhi on the night of January 17 this year. This happened a day after her twitter spat with Pakistani journalist Mehr Tarar over the latter's alleged affair with Tharoor.
Delhi Police set up a Special Investigation Team a few days after Pushkar`s death to probe the case as it occurred a little over three years after the marriage.
Under the law, every death of a bride within three years of marriage is viewed with suspicion that it may be a case of dowry death.
The case of Sunanda's death has seen many twists and turns and has been a matter of controversy.
In March this year, the police had said that her viscera report had hinted towards drug poisoning but its findings were still inconclusive to file an FIR in the case.
Police sources had said then that investigators would now take the opinion from the panel of doctors from AIIMS which had carried out an autopsy to shed light into findings of the Central Forensic Science Laboratory report.
The autopsy report that time had mentioned more than a dozen injury marks on Sunanda`s both hands and an abrasion on her cheek which suggests a 'use of blunt force', besides a 'deep teeth bite' on the edge of her left palm.
The search and seizure memorandum of the police had mentioned finding of mix of two drugs - Alprazolam and Excedrin.
The probe into the case was handed over to the Crime Branch on January 23 this year. However, the case was transferred back to the South District Police two days later on January 25.
