Jayalalithaa's death a natural death or murder?

Still there is no clarity over former CM of Tamilnadu, Jayalalitha's demise as many doubts remained unanswered so far. It is known that Jaya joined hospital on September 22, last year and died on 5 December after 75 days fight for life. These 75 days treatment remained a secret till today. Many film actors in Tamilnadu and other bigwigs also demanded for a probe while claiming Sasikala's conspiracy as the reason behind Jaya's death. EPS didn't appoint a commission and chief justice over the probe of the death mystery so far.
