Giving a blow to the prosecution in the 1999 hit and run case involving Sanjeev Nanda, a forensic expert told the court that the reports on the alcohol content of Nanda and his blood sample are corrupt and cannot be relied upon. Nanda is accused of mowing down six people under his speeding car.
During cross examination by defence counsel Ramesh Gupta, Doctor VN Sehgal told Additional Sessions Judge Vinod Kumar that a wrong method was used to estimate the alcohol content in Nanda’s blood and there were flaws in the computing process in which various scientific considerations were given a go by.
Sharma, then a resident doctor at AIIMS, had performed the ‘blood alcohol estimation test’ on Nanda, grandson of former Navy Chief SM Nanda, on January 10, 1999, following his arrest allegedly for driving in a drunken state and mowing down six people with his black BMW car near Lodhi Hotel.
The counsel also put questions to Sehgal on the report by Chakotra, a blood examiner, who had claimed the blood sample lifted from the steering of the car was of B group but it was not possible to determine whether it was B-positive or B-negative.
“Detection of blood systems, including the RH factor (determining the positivity and negativity) pose no difficulty upto 26 weeks,” Sehgal said.
He further told the court that the reports were bound to be misleading, as they were prepared only from one blood sample and no preservatives, which lead to non-credible analysis, were added.
Chakotra’s report had boosted the prosecution’s case, as it had suggested the sample found on the steering of the car was of B group, same as that of Nanda.
The prosecution would now cross-examine Sehgal on January 17, the next day of hearing.
