Preliminary examination of the skeletal remains taken from the drain adjacent to Noida businessman Moninder Singh Pandher's house indicate that the bones recovered did not date back to more than two years, CBI sources said.
The individualisation of body parts for their identification, skeletal remains and other things were being done round-the-clock by scientists and doctors in AIIMS and Forensic Sciences Laboratory.
The CBI said only 15 skulls had been found so far and not 17 as claimed by the Uttar Pradesh police so far and sent to AIIMS.
Sources said the skeletal remains had been sent to All India Institute of Medical Sciences for examination including the photo imaging of the skulls and individualisation of bones.
The finger and foot prints had been sent to Hyderabad for the same purpose along with the bio-material, including viscera, found near the house of Pandher who, along with his servant Surendra Koli, are the main accused in the case and in CBI's custody till January 25.
