Today is the second death anniversary of Sunanda Pushkar. Despite being a high-profile murder case, the investigative agencies have little to show for their efforts 2 years after she was found dead in a hotel in New Delhi. Albeit a new revelation comes up every second month, the case is nowhere near its conclusion.

To refresh your memory and bring you up to date with the murder mystery, NewsGram presents a timeline of events that followed Sunanda Pushkar's death.

19^th January, 2014: After her post-mortem at AIIMS, doctors term her death as 'sudden, unnatural'. The autopsy report pointed towards a case of poisoning and stayed quiet on the question of suicide. The report also noted over a dozen injury marks on her hands and a 'deep teeth bite' of her left palm. It also overruled 'drug overdose'.

21^st January, 2014: A sub-divisional enquiry, which is ordered in case the wife dies before seven years of marriage, concludes that she died of poison and directed the investigative agencies to probe this angle.
