The CBI wanted to get the second post-mortem examination conducted as they wanted to get some doubts cleared about the rape and murder theory as floated by family members and local residents. Sources said that the CBI is probing into the honour killing angle as well as the property dispute, which had come up during probe by the UP police. Sources said that the CBI is advocating second autopsy as they were not satisfied with the first post-mortem examination, in which one of the three doctors, Dr Pushpalata Pant, was conducting the job for the first time, while the panel also remained silent over from where the blood found near the private part of the younger girl came from, whether it was human blood, the time of death of the two girls, expert opinion over the finding that the death is result to asphyxia as a result of anti-mortem hanging etc.
