The Central Bureau of Investigation Tuesday said that dentist Rajesh Talwar had found his daughter and domestic servant in "objectionable position" and killed them using his golf stick and a sharp-edged weapon.
Deposing during cross examination in a special court in Ghaziabad, CBI Additional SP AGL Kaul, who led the second probe team, went into the motive behind the sensational double murder of 14-year old Aarushi and domestic servant Hemraj at the Noida residence of dentist couple Rajesh and Nupur Talwar on the intervening night of May 15-16, 2008.
Kaul said according to his investigation Rajesh Talwar was awake in his room at 12 midnight whereas the time of murders, according to postmortem report, is between 12-1 am.
The officer claimed that according to his probe Hemraj was attacked in Aarushi's room on her bed, taken to the roof and dragged to a corner where his throat was slit.
Explaining the sequence of events which took place on the fateful night, Kaul said Rajesh heard some noise and went to Hemraj's room but did not find him there.
"There were two golf sticks lying in Hemraj's room one of which Rajesh Talwar picked up. He heard a noise from the room of Aarushi. The room door was not locked and was just shut. He opened the door and found Aarushi and Hemraj were in objectionable position on the bed of Aarushi," Kaul said in his testimony.
Kaul said finding them in such a position, Rajesh Talwar hit on Hemraj's head with golf stick. By the time he gave a second blow the servant's head moved from the position and the stick hit Aarushi on her forehead.
He said when golf sticks were seized the stick heads were not sealed separately.
"The V or U shaped injury on Aarushi's forehead could have been caused by the use of golf stick head," he said.
The officer said the noise generated in the process awoke Nupur Talwar who rushed to Aarushi's room.
"By the time the injured Hemraj had fallen from the bed. Both checked the pulse of Aarushi and found her near-dead which scared them and planned that the servant should be executed so that no one comes to know about the incident," Kaul said before the court.
He said both decided to hide the body of Hemraj and dispose it of on getting suitable opportunity.
The duo wrapped Hemraj's body in a bed-sheet and dragged him to terrace where they slit his throat, covering the body with a cooler panel, Kaul said.
He said after coming to the room, they dressed up the crime scene by arranging the bedsheet and toys.
They slit Aarushi's throat, to ensure that wounds on Hemraj and their daughter look similar, and Nupur cleaned her private parts, he said.
Giving details of his findings, the officer said the dentist couple cleaned blood stains, disturbed the router, collected all the clothes which were used to clean blood and also the small sharp edged weapon used in the killing with an intention to dispose them off.
"They cleaned the golf stick which was used in the murder and hid it in the loft of Aarushi's bedroom. They locked the door of Aarushi's room from outside. They locked the outermost door from inside and wooden door from outside and entered the flat through Hemraj's room, the door of which opened between these two entry door," he said.
Both waited for their maid Bharti to come while Rajesh kept drinking liquor all this time.
The officer said once Bharti came, Nupur asked where is Hemraj as the wooden door was locked by them from outside.
"She threw the key towards Bharti from balcony which can be approached from the backside of Aarushi's room...When Bharti came up she found Talwars crying and saying 'see what Hemraj has done?'" he said.
On being questioned by defence about forensic reports that Hemraj's DNA was found from a purple pillow recovered from the residence of Krishna, who was a suspect in the initial probe done by CBI, Kaul said that was the result of typing error in the CFSL report.
"I cannot give any specific reason which made me believe that there was a typing error in the report. It is wrong to say that I am intentionally not telling the reasons on the basis of which I deduced that there was a typing error in the report," Kaul said.
He said he had written to Director, Centre for DNA Fingerprinting and Diagnostics, which conducted DNA test, seeking explanation for the alleged error.
"I had written that I feel that description of purple coloured pillow cover recovered from Krishna's room and pillow recovered from Hemraj were inter-changed," he said.
