Sharma, the former head of forensics at AIIMS, had conducted the postmortem on Aarushi's body in 2008. According to Sharma, Aarushi might have been killed 4-6 hours after having her dinner as there was undigested food in her stomach.
Recording his statement in the court, Sharma said, "If a child who is around 14-years-old child is lying on the bed and has a wound that measures 8 cms/2cms, then she would fall unconscious immediately and would not be able to raise an alarm."
The witness, however, told the court that Aarushi's neck was slit in one stroke using a scalpel number 10. Scalpel number 10 is usually used during postmortems by surgeons, pathologists and anatomy specialists, explained Sharma.
The Talwar couple earlier had moved the Allahabad High Court challenging special CBI court's order which had rejected their plea. The high court reserved its verdict till July 16.
Rajesh and Nupur Talwar had urged the court to ask CBI to submit all documents and evidence gathered during narco-analysis, brain mapping, sound simulation test and lie detector test. The couple also urged the court to direct the investigative agency to summon other witnesses to the court.
Additional Sessions Judge Shyam Lal had turned down the application, saying that it was filed to delay the proceedings.
