Ghaziabad, Apr 16 (TNN): A Central Bureau of Investigation (CBI) officer probing the sensational Aarushi Talwar-Hemraj double murder case told a special CBI court on Tuesday that the murders were committed by Rajesh and Nupur Talwar.

CBI investigation officer AGL Kaul told the CBI court that it was impossible for someone to enter the house and commit the crime. Kaul said Aarushi was murdered by her parents Rajesh and Nupur Talwar.

No one from outside could have come inside the flat and committed the crime, the officer told the court.

Aarushi Talwar, 14, was found dead with her throat slit in her parents' home at Jalvayu Vihar in Noida on 16 May 2008. Hemraj's body was found on the terrace of the flat a day after.

During the previous hearing on April 9, an official of the Gujarat Forensic Science University (GFSU) had told the court that the crime was possibly committed using a golf club and surgical knife, adding that no outsider except the Talwar couples was involved in the murder.

While the injury on their heads was that of something like a golf club, the neck wounds were inflicted using a sharp-edged thing like a surgical knife, GFSU director Mohendra Singh Dahiya had told the court.

The injury marks indicated that their throats were slit after the murder, he added.

"I don't know who was attacked first, but they were certainly killed on Aarushi's bed. A golf club, or any similar thing like a hockey stick, was used for the murder, after which their throats were slit using some sharp-edged thing like a surgical knife," he had told the court.

The two were murdered after being found in a compromising position in Aarushi's room, he said.

After killing Hemraj, the murderers took his body on the terrace in a bed sheet, during the course of which one of them lost control, leading to blood-stained hand marks on the wall along the terrace door.

Dahiya told the court that GFSU joined the investigations after being approached by CBI in October 2009.
