In April last year, a 30-year-old law student was found murdered at her home in Kerala's Ernakulam, her naked body bearing marks of extreme torture. A court in Kochi today held a migrant worker from Assam, Ameer-ul-Aslam, guilty of Jisha's rape and murder. As the judgement was being pronounced, the convict said thrice: "I am innocent, the police just arrested me and took me away." He will be sentenced tomorrow.
