New Delhi, April 16: The CBI team probing the May 2008 murder of Aarushi Talwar today told a court the Noida teenager was killed by her own parents, as “no one from outside” could have entered the house and committed the crime.

“No one from outside could have come inside the flat and committed the crime. It has been committed by the accused only,” additional SP A.G.L. Kaul, the head of the investigating team, said.

Aarushi’s parents, dentist couple Nupur and Rajesh Talwar, who are both out on bail, sat silently through the proceedings in the special CBI court in Ghaziabad.

Kaul also said the couple murdered both Aarushi and their domestic help Hemraj, the initial suspect. The assertions came after an investigation that has spanned nearly five years and involved two state police forces before being handed over to the central agency.

Aarushi, 15, was found dead at her Noida home with a head injury and her throat slit on May 16, 2008. Hemraj’s body was found a day later on the terrace.

Uttar Pradesh police had first probed the murder. The case was then transferred to Delhi police, before the CBI took over.

Kaul said the “house has only one entrance and exit and no one could (have) come in and committed the crime”. He ruled out the involvement of the other suspects — Talwar’s compounder Krishna, and a neighbour’s help, Vijay — and the help of a family friend, sources present in the court said.

The case is being tried under Section 123 of the Criminal Procedure Code, which bans the media from being present in the courtroom.

Sources said Kaul’s submission was based on a 2010 closure report the CBI had filed, which said although the agency had no concrete proof to establish that the Talwars were guilty, circumstantial evidence supported its theory.

“The findings of the investigation reveal a number of circumstances that indicate the involvement of the parents in the crime and the cover-up. However, there are a number of critical and serious gaps in the circumstances which make it difficult to string together the sequence of events and (the) motive behind the gruesome murder,” the CBI had said in the report.

The agency had asked the court for permission to close the case for lack of evidence. But the judge had said there was enough circumstantial evidence to get the Talwars to stand trial.

Aarushi’s parents claim the CBI is accusing them of the murders because it has not been able to find the real killer.

Since the trial began last year, 39 witnesses, including Kaul, have deposed before the court.

At the previous hearing on April 9, an official from the Gujarat Forensic Science University had told the court the crime was possibly committed with a golf club and surgical knife and no outsider, except the Talwars, was involved.
