Forensic experts from different parts of country explain at a conference in Bhopal how advances in this technique can help to crack many crime cases and collect clinching evidence against suspects
Bhopal: The antelope killed by actor Salman Khan was a blackbuck and not a common deer. It was confirmed through DNA fingerprinting. DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA.
The forensic report that was initially received after the hunting of blackbuck mentioned that a deer had been killed. But an officer of the forest department expressed doubt that it could be a blackbuck. In fact, blackbuck is a rare species and there is provision of more stringent punishment for killing this species of deer. Later the DNA fingerprinting made things clear. This was disclosed by Dr GV Rao, a forensic expert of Hyderabad, in the forensic update conference at AIIMS, Bhopal.
He said that at that time we did not have any such technique to find out whether the animal killed was a common deer or a blackbuck. Later, we developed the technique for it and it was confirmed that the animal killed was a blackbuck. Only then did the verdict was given in the case.
DNA finger printing helped to crack Naina Sahni murder case
According to Dr. Rao, in 1995, Congress worker Naina Sahni was murdered by her husband and Congress leader Sushil Sharma. The body was chopped into pieces and put in a clay oven to burn. Only a part of leg remained in the tandoor, the rest of the body was burnt. DNA fingerprinting was done by taking the samples from the leg and it was confirmed that the deceased was Naina Sahni.
Dr Rao said that during the assassination of former Prime Minister Rajiv Gandhi, it was not immediately known where the explosion occurred. The body parts of the people were scattered. Dhanu, the carrier of the bomb, was blown up. During the investigation, a piece of belt was recovered from the spot with blood and flesh on it. Later it became clear that Dhanu was the human bomber.
Prof. OP Murthy, a forensic expert of AIIMS Delhi, said that special care should be taken while taking DNA samples.
Gang-rape accused cannot escape punishment
According to the forensic experts, all the accused can be caught if a woman has been gang-raped. Earlier it was not possible to ascertain the identity of all persons who raped the woman as the sperms entered inside her body simultaneously. But now there is a technique to separate the sperms. So the culprits of gang-rape cannot escape punishment now.
Skeleton suspected to be of woman was found to be of man
Dr Pankaj Shrivastava, a forensic expert of Sagar DNA Lab, said sometime back a human skeleton was recovered and the doctor performing the autopsy opined that it belonged to a woman on the basis of shape of the skull and his own experience. But the DNA fingerprinting revealed that it belonged to a man. Thus this technique is used to gather clinching evidence in crime cases, Dr Shrivastava said.
