Dentist Rajesh Talwar killed his daughter Aarushi and domestic help Hemraj using his golf stick and a sharp-edged weapon after finding them in the same room, the CBI told a Ghaziabad court on Tuesday.
Deposing before a special court, CBI Additional SP and Investigating Officer AGL Kaul explained the sequence of events and circumstantial evidence on the night when the double murder took place.
Fourteen-year old Aarushi, daughter of dentist couple Rajesh and Nupur Talwar, was killed at their Noida residence on the night between May 15-16, 2008. Hemraj's body was found on the terrace a day later.
Kaul, who was cross-examined by the defence counsel, said Rajesh heard some noise and went to Hemraj's room but did not find him there.
"There were two golf sticks in Hemraj's room, one of which Rajesh Talwar picked up. He heard a noise from Aarushi's room. The door was not locked and was just shut. He opened the door and found Aarushi and Hemraj…," Kaul told the court.
Talwars' counsel Tanvir Ahmed Mir rubbished the CBI's theory, saying it was based on assumptions and surmises and nothing was available on record to prove it.
Kaul said Rajesh was awake in his room at 12 midnight whereas the time of murders, according to the post-mortem report, is between 12 midnight and 1 am. According to his probe, Hemraj was attacked in Aarushi's room and taken to the roof where his throat was slit.
Kaul said Rajesh hit Hemraj's head with a golf stick. By the time he gave a second blow, the servant's head moved and the stick hit Aarushi on her forehead.
The IO said the noise awoke Nupur Talwar. Both got scared after finding Aarushi almost dead. Then they decided to kill the servant so that no one comes to know about the incident, Kaul said. They slit Aarushi's throat to ensure that wounds on both the bodies of both the deceased looked similar, he said.
"They cleaned the golf stick used in the murder and hid it in the loft of Aarushi's bedroom. 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 the two entry doors," he said.
On being questioned by the 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.
