Kolkata Doctor Case: Post-Mortem Report Clarifies 150 Grams As Uterus Weight, DNA Analysis To Follow

Senior forensic scientists and police officers have clarified that DNA analysis will be crucial in identifying the number of individuals responsible for the crime. The post-mortem report of the Kolkata doctor, who was allegedly raped and murdered, has dismissed claims about 150 grams of semen found on her body. Instead, it specified that the 150 grams referred to the weight of the victim's internal genitalia, particularly the uterus.

The forensic team arrived at the crime scene nearly five hours after the incident. By then, any fluids had turned into a smear. They collected samples from affected areas but no liquid or fluid was gathered as it had already congealed. These samples included residual blood, semen, and vaginal swabs.

Forensic Analysis and DNA Profiling

The collected samples were submitted to the Central Forensic Laboratory in Kolkata on August 12, three days after the crime occurred. A senior police officer mentioned that collecting forensic elements, storing them properly, completing paperwork, and submitting them to the central forensic laboratory follows a protocol that takes time.

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 Kolkata Police. This report will include detailed DNA profiling to identify those involved in the crime.

News18 accessed exclusive details from the post-mortem report and investigation notes which may cast doubt on social media claims about semen quantity found on the victim's body. The post-mortem was conducted by a panel of three doctors, including two women forensic scientists-doctors from RG Kar Medical College and NRS Medical College.

Key Role of Uterus in Forensic Examination

A senior central forensic scientist explained that the uterus is crucial for preserving fluids like swabs or semen for a long time. "Once collected and put inside a machine for DNA profiling, there cannot be any external influence whatsoever," said the scientist. The profiling process takes time but delivers almost accurate results.

The scientist elaborated on preserving and quantifying evidence in this case. The uterus of the victim was preserved with its weight documented at 150 grams. Collected samples mixed with other bodily fluids were examined by 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," added another senior scientist.

Clarifications on Social Media Claims

Senior forensic scientists emphasized that documenting organ weights is standard practice in post-mortem reports. In this case, 150 grams pertained to anatomical measurements rather than fluid quantity. This clarification counters misinformation circulating online about semen quantities found on the victim's body.

Students joined other protesters in a midnight rally demanding proper investigation into the murder of a 31-year-old post-graduate trainee in Kolkata. Senior forensic scientists reiterated that DNA analysis would be crucial in determining how many individuals were involved in this crime.

The case hinges significantly on DNA profiling results expected soon from Kolkata's Central Forensic Laboratory. These findings will play a pivotal role in identifying perpetrators and ensuring justice for the young doctor whose life was tragically cut short.
