28 said both girls died of asphyxia due to ante mortem hanging. There was post mortem staining on lower part of body, perineal findings suggestive of rape.
Multiple vaginal tears, vaginal discharge and bluish colouring in the perineal areas were found in the elder cousin. The younger girl had a blood clot in the vaginal area, and clots and abrasions around the hymen.
On June 7, Uttar Pradesh DGP A L Banerjee said it was possible that one of the girls had not been raped, and that the killings might have been triggered by a property dispute. CBI carried out polygraph tests on the accused on June 26, and on the fathers of the two victims, an uncle and an eyewitness, on July 7.
In late July, the CBI set up a medical board comprising three AIIMS doctors headed by Dr Adarsh Kumar. On July 17, the agency announced it intended to exhume the bodies for another autopsy. But attempts at exhumation were suspended on July 20 due to flooding in the Ganga.
