The two accused, Moninder and his cook Surendra Koli, were flown to Ahmedabad yesterday. Rathore said: “We have prepared a comprehensive questionnaire of 30-40 questions to which the two accused would be subjected during the test.” Rathore said the tests might take at least three days. The accused are in police remand till January 10.

“Apart from the possibility of organ trade and child pornography rackets, the Noida police also wanted to know if there was any one else involved in the case and that what was his profession,” said a source.

Noida police, which according to sources are still groping in dark for the actual reason for the murders, are now pinning their hopes on the possibility of Moninder and Koli revealing fresh facts before experts in a state of trance.

A team of forensic experts from the Central Forensic Lab in Agra visited D-5 today. The Special Investigation Team (SIT) formed under the command of Rathore went through the evidence the police had collected.

Another police team is camping in Mumbai looking for alleged pimp Neelam. It was she who introduced Payal to Moninder. Police suspect Neelam could have the keys to some of Moninder’s secrets.
