The post-mortem report of the Kolkata doctor who was allegedly raped and murdered has dismissed claims floating on social media quoting reports of 150 grams of semen, or even 150 mg of semen found on her body. The actual post-mortem report has specified that the 150 grams mentioned refers to the weight of the victim’s interior or internal genitalia, particularly the uterus, and not the weight of any fluid.
Forensic scientists and doctors always document the weight of organs in such reports, and in this case, the 150 grams pertains to anatomical measurements, not fluid quantity, a senior forensic scientist, who has seen the post-mortem report, told News18.
In a crucial development in the case of the gruesome death of a young doctor at RG Kar Medical College and Hospital, News18 has accessed exclusive details from the post-mortem report and investigation notes, which may cast doubt on the claims circulating on social media and otherwise about the quantity of semen found on the victim’s body. The post-mortem was conducted by a panel of three doctors, which include at least two women forensic scientists-doctors. The team consisted two doctors of RG Kar Medical College and another from NRS Medical College.
The forensic team, arriving at the crime scene almost five hours after the incident, found that the fluids had turned into a smear. They collected samples from the affected areas and surface, but no liquid or fluid was gathered, as it had already congealed.
The collected samples, including any residual blood, semen, and vaginal swabs, were submitted to the Central Forensic Laboratory in Kolkata on August 12, three days after the crime was committed. The process of collecting forensic elements, storing it properly and doing the paperwork and submitting it to the central forensic laboratory needs to go through a protocol which takes time, said a senior police officer.
The report from the Central Forensic Laboratory is expected by Wednesday and will be forwarded to the Central Bureau of Investigation (CBI), as authorised by the Kolkata Police. This report will include detailed DNA profiling to identify the perpetrator or perpetrators involved in the crime. Senior forensic scientists and police officers have clarified to News18 that the DNA analysis will be crucial in determining the exact number of individuals responsible for the crime.
Case Hangs in Balance on DNA Profiling
News18 spoke with senior forensic experts, who have served in central forensic laboratory and other senior IPS officers who have worked in detecting sensitive and complicated cases of rape and murder. According to the senior central forensic scientist, the uterus is the crucial organ that preserves the fluid, swab or semen for a really long time.
“Once it is collected and put inside the machine for DNA profiling, there cannot be any external influence whatsoever. The profiling takes time, but it delivers almost accurate results,” said the senior scientist.
The scientist elaborated the critical details related to the preservation and quantification of evidence in the case. In this specific case, the uterus of the victim – a key organ in forensic examination, was preserved and its weight was 150 grams, as it was documented. The collected samples, including any residual blood, semen and vaginal swab, were mixed with other bodily fluids and examined by a panel of experts.
“The DNA samples can come in detail. It will show if the DNA is of one person or if it is mixed, as in case of multiple perpetrators,” he added.
