The theory that a radioactive substance had caused the death of Sunanda Pushkar has been junked by a FBI forensic report which has been received by the Delhi police. The Delhi police probing the death of Sunanda Pushkar had sent viscera samples to the FBI for forensic analysis.
The report received by the Delhi police completely rules out death due to radioactive substance. The Delhi police had sent the samples to the FBI lab in Washington earlier this year after it was suggested that a radioactive substance known as polonium could have been used to poison Sunanda Pushkar.
As the labs in India cannot determine the presence of polonium. The viscera samples were sent to the FBI lab in Washington where it was determined that there was no radioactive substance present.
Sunanda Pushkar, 51, was found dead at a hotel in New Delhi in January 2014. While it was stated at first that the death was due to natural causes, the case was re-opened and charges were murder were registered against unknown persons.
