"Seven forensic reports were to be received in Mohanlalganj murder case, of which, only two have been received so far and on the basis of which any conclusion cannot be drawn," Senior Superintendent of Police Praveen Kumar told PTI.
"I can say that the two reports received so far are suggestive and not conclusive. I can say that these reports do not contradict our finding so far."
He said any conclusion could be drwan only after all the seven reports are received and corroborated.
"Whatever comes to the fore will be shared with the media, but it is not right to speculate at this level," Kumar said.
The victim, who hailed from Deoria district, was found brutally murdered on July 17.
ADG Sutapa Sanyal, who was handed over the investigation, on July 20 claimed that the crime was committed by a security guard, Ram Sewak, when the woman resisted his rape bid. She had claimed that there was no rape.
Sanyal had also claimed that nail scratches were detected on Ram Sewak's body, which were probably caused during struggle between him and the woman.
However, some media reports questioned the police theory, suggesting that the woman was killed by more than one person after rape.
Meanwhile, Union minister of Medium, Small and Medium Enterprises Kalraj Mishra on Sunday demanded a CBI inquiry in the case.
"The manner in which the case is being twisted, I feel that there is no other option but a CBI inquiry. The police theory has so many loopholes that it has turned out to be laughable," he said.
