New Delhi: Delhi Police have sent Congress leader Shashi Tharoor's wife Sunanda Pushkar's three mobile phones and a laptop for forensic examination at CFSL, Gandhinagar in Gujarat, as per reports on Tuesday.

Police have reportedly said that they were trying to join the dots to establish the exact sequence of events when Sunanda's body was found in a posh hotel room in Delhi.

Top brass have also said that they were hopeful of cracking the case, reports said.

On October 19, 2014, it was reported that poison had been found in the final viscera report of Pushkar.

The viscera report had been submitted by AIIMS doctors to Delhi Police on September 30. The three-member team had submitted the 'Subsequent Medical Board Opinion' to the police.

The new report by the panel of doctors, who had conducted the autopsy on her, was prepared on the basis of the findings of the Central Forensic Science Laboratory (CFSL) which had examined Sunanda's viscera, sources had said, as per PTI.

They said that the team had again concluded like it did in its first report that her kidney, liver and heart were functioning normally and that her death was caused by poisoning.

In July this year, Tharoor had sought a speedy inquiry for a 'clear and definitive conclusion' as to the cause of death of his wife in the wake of reported claims by a senior forensic doctor that he was pressurised to manipulate the autopsy report in the case.

Dr Sudhir Gupta, who was the head of the forensic science department of AIIMS and led the panel that conducted Sunanda's post-mortem, had alleged that he was pressurised to show her death was natural, which he resisted.

Sunanda was found dead at a five-star hotel in South Delhi on the night of January 17 this year. This happened a day after her twitter spat with Pakistani journalist Mehr Tarar over the latter's alleged affair with Tharoor.

Delhi Police set up a Special Investigation Team a few days after Pushkar`s death to probe the case as it occurred a little over three years after the marriage.

Under the law, every death of a bride within three years of marriage is viewed with suspicion that it may be a case of dowry death.

The case of Sunanda's death has seen many twists and turns and has been a matter of controversy.

In March this year, the police had said that her viscera report had hinted towards drug poisoning but its findings were still inconclusive to file an FIR in the case.

Police sources had said then that investigators would now take the opinion from the panel of doctors from AIIMS which had carried out an autopsy to shed light into findings of the Central Forensic Science Laboratory report.

The autopsy report had mentioned more than a dozen injury marks on Sunanda`s both hands and an abrasion on her cheek which suggests a 'use of blunt force', besides a 'deep teeth bite' on the edge of her left palm.

The search and seizure memorandum of the police mentioned finding of mix of two drugs - Alprazolam and Excedrin.

The probe into the case was handed over to the Crime Branch on January 23 this year. However, the case was transferred back to the South District Police two days later on January 25.
