The discovery of several bundles containing parts of human torsos has led Central Bureau of Investigation sleuths to believe it was unlikely that Moninder Singh Pandher and Surinder Koli, the main accused in the serial killings at Nithari in Noida, had links to illegal organ trade.

The CBI team probing the grisly murders has found more than a dozen bundles containing body parts in the home of Pandher and drains near it, agency sources told PTI on Sunday.

The bundles, containing parts from the torsos of bodies, were found after the CBI took over the probe into the serial killings of women and children from Uttar Pradesh Police last week, the sources said.

Till now, police had not found any parts from the torsos of the 17 people killed at Nithari, giving rise to speculation that Pandher and Koli might have been involved in illegal organ trade.

After interrogating Koli, the CBI has come to the prima facie conclusion that he is a psychopath who used to carry out the killings, the sources said, adding that Pandher's involvement in the murders could not be completely ruled out.

The sources also said that the Uttar Pradesh Police had not acted efficiently even after the grisly crimes came to light. Parents of the murdered children have complained that police at Nithari had failed to act on their repeated complaints about their offspring going missing. Action was taken against several policemen after the crimes were uncovered.
