New Delhi, Nov 14: Delhi Police are considering sending the viscera samples of former Union minister Shashi Tharoor's wife Sunanda Pushkar to a forensic laboratory abroad to determine the type of poison that might have caused her death.
The AIIMS medical board had, in its second report submitted to the police recently, confirmed that Pushkar had been killed by poison.
The, report, however did not mention the type of poison that caused Pushkar's death.
They had suspected the use of some poison that had radioactive isotopes in it that labs in India couldn't detect.
A senior police officer said the police were mulling sending the viscera samples to a UK-based laboratory that had facilities to test all kinds of poisons.
"It is almost clear that Pushkar died of poisoning. The biggest question now is what kind of poison was used and how did it reach her body. If these are answered, the case could head to its logical end," the officer said on condition of anonymity.
For now, the police have asked the AIIMS panel of doctors to redo their investigations and name the poison that might have caused Pushkar's death. But if the AIIMS team fails to do so, then the samples will be sent abroad.
The police have already seized three mobile phones and a laptop of Pushkar and sent them to a forensic laboratory in Gandhinagar, Gujarat, to check whether anything was deleted from the gadgets after her death.
On Thursday, the police questioned some people related to the case but senior officials refused to divulge their identities.
