However, what shocked many was that the panel did not name the specific poison or chemical that caused the death. Instead, it listed a number of poisons that cannot be detected in Indian labs.
The list of poisons include thallium, polonium 210 (a radioactive substance of which a few milligrams is lethal), nerium oleander, snake venom, photolabile poisons and heroin.
Hinting at unnatural death, the panel of doctors also reiterated that Sunanda, the wife of Congress leader and former Union Minister Shashi Tharoor, was neither ill nor had any disease prior to her death.
The panel said, "She was a normal healthy individual. She was also investigated for systemic lupus erythematosus but did not have it."
Sunanda was found dead in a star hotel in Delhi. Sunanda's death shocked the nation as she was engaged in an online spat with a woman from Pakistan ahead of her death.
