Kayamkulam Kochunni
However, Kochunni's death is disputed. Another record cites he was imprisoned at Central Prison, Poojappura in his 70s. Some researchers states that it was after the success of the 1966 film that the present account of his death (that he died in September 1859, aged 41) was popularized and dominated while the other account diminished, the movie used the former since it was more suitable for the film's commercial success. As per the other record, he escaped and lived another 36 years. He died at the age of 77 from Tuberculosis at the cow barn of Thoppil "tharavadu" (family of Thoppil Bhasi) in Vallikunnam. He was staying there undercover as a steward and farm-hand of the family. A woman from the house took care of him during his final days, who was the only one aware of his true identity.
