On a day the Delhi police filed a case of murder in the death of Sunanda Pushkar, Congress leader Shashi Tharoor's wife, came another twist. Though various reports have suggested that death was due to poisoning, it took the police almost a year to file a First Information Report or FIR under Section 302, or murder, of the Indian Penal Code. The reason, the police have indicated, was due to the All India Institute of Medical Science or AIIMS using the word 'homicidal' in its clarification report, submitted on December 29, 2014.
