New Delhi: The DNA analysis and advanced scientific techniques, including the finger print analysis and odontology report (relating to teeth bite marks), led to the Delhi court convicting the four men in the December 16 gang-rape and murder of the 23-year-old girl in a moving bus.
The DNA analysis, finger prints lifted from the bus and the analysis of the bite marks on the body of the girl, was appreciated by the court so much so that the judge, while concluding his 237-page judgement, lauded the manner in which the Delhi Police made use of scientific tools in building its case against the accused persons and proving their guilt.
"DNA analysis duly establishes the identity of the victim and of the accused persons beyond doubt to be the persons inside the bus at the relevant time," Additional Sessions Judge Yogesh Khanna said.
"Besides the identity of the accused being established by the traditional method, their identity and presence is even otherwise confirmed by sceintific reports viz DNA, finger printing and odontology report," he said.
In odontology report, the bite marks on the victim`s body were matched with the teeth of accused based on scientific principle that alignment of teeth is peculiar to every individual.
"The report establishes the bite marks of accused Ram Singh and Akshay on the person of the prosecutrix," the ASJ said.
Dealing individually with every accused, the court noted the swab from the victim`s body matched with the DNA sample of Ram Singh, the prime accused who was found dead in Tihar jail during the pendency of the trial.
"DNA profile developed from blood stains found on the T-shirt and slippers of accused Ram Singh matches with the DNA profile of the prosecutrix (girl).
"The DNA profile developed from blood stains from both the iron rods recovered at the instance of accused Ram Singh from the bus is of female origin and was consistent with the DNA profile of the prosecutrix," it added.
The DNA samples were also lifted from the curtains, and seats of the bus, blood stains near the gates, below the seats in the sixth row and they all matched with that of the victim.
The DNA profile developed from the sample of blood of the girl matched with that developed from the stains from Vinay Sharma`s undergarments, clothes and slippers.
To infer the guilt of accused Pawan Kumar, alias Kaalu, the court noted "the DNA profile developed from the sweater of Pawan matched with DNA profile developed from the blood of the girl and separate DNA profile matched with that of the complainant (male friend)," the judge noted.
As regards Mukesh and Akshay, the court noted that the DNA profile developed from blood stains on their clothes, breast swab of the girl matched with the DNA of the victim and the complainant.
Further, DNA profile found on biological samples lifted from metaril objects such as bus, iron rods, ash, unburnt pieces of clothes, curtains, hair matched with the DNA profile of the complainant.
Dealing with the finger print report, the court said "a bare perusal of the report would show the chance print lifted from inside the bus was found to be identical with left finger print specimen of accused Vinay Sharma.
"Further, other chance print was identical with right thumb impression of Vinay," the court noted.
