The chargesheet which runs into 1,500 pages has statements of witnesses including Ameer's friends along with Jisha's neighbour who claims to have seen the accused leaving Jisha's house after the murder. The police say Ameer had entered the house with the intension of raping Jisha but hit her sharp objects after she resisted which led to her death.
