Synopsis
The FSL in Gandhinagar is conducting 24/7 DNA profiling to identify victims of the Ahmedabad plane crash. Director H.P. Sanghvi explains the meticulous process involved in forensic identification, emphasizing the challenges faced during this critical operation.
Key Takeaways
- FSL operates 24/7 to identify crash victims through DNA.
- Two methods are used for DNA sampling: blood and remains.
- Strict quality control is maintained during the DNA matching process.
- Identification requires matching at least 23 alleles.
- Former CM Rupani's identity was confirmed via DNA testing.
Ahmedabad, June 15 (NationPress) The Forensic Science Laboratory (FSL) located in Gandhinagar, Gujarat, is functioning continuously to identify victims of the recent Ahmedabad plane crash utilizing DNA profiling and matching techniques.
During a media briefing, FSL Director H.P. Sanghvi shared comprehensive details about the complex and time-consuming process involved in forensic identification.
“The complete procedure—from gathering DNA samples from victims and their relatives to the final matching—is being executed 24/7,” Sanghvi stated.
He elaborated that DNA sampling is performed using two main techniques. “The first method involves collecting fresh blood samples from relatives, which is relatively easy. On the other hand, the second method—extracting DNA from the remains of the deceased—is considerably more intricate and requires precision,” he explained.
Samples collected from the deceased, like bones or teeth, are meticulously cleaned to remove any external contamination. “If the sample is a bone, it’s ground into powder. If it’s a tooth, it’s broken into small pieces and subsequently powdered. The DNA is then isolated using specialized machines at controlled temperatures,” Sanghvi continued. The extracted DNA undergoes quality and quantity assessment using RT-PCR machines. Only DNA that meets the required quality standards is replicated.
The DNA strands are separated and processed through sequencing machines to create a complete DNA profile. However, Sanghvi warned that if sufficient DNA alleles are not identified, the entire procedure must be restarted. “Identification can only be confirmed when 23 alleles match between the victim and their family members,” he noted.
In cases involving father-son relationships, additional Y-chromosome testing is performed to verify identity. He highlighted the complexity of this work, stating, “Despite the technical hurdles and the time involved, FSL has successfully identified a substantial number of victims in record time with high accuracy.”
In the meantime, the identity of former Gujarat Chief Minister Vijay Rupani has been officially validated through DNA testing, just three days after the tragic crash of Air India flight AI171. This confirmation was made at 11:10 a.m. on Sunday, following exhaustive forensic analysis at the Gandhinagar FSL lab. Rupani's remains are set to be transported from Ahmedabad to Rajkot via a chartered flight.
Sources close to the family disclosed that Rupani had canceled his ticket twice before finalizing travel plans for June 12. Initially booked in seat 11G in the same row as the sole survivor, Vishwas Kumar, he switched his seat at the last minute to 2D in business class. Despite typically preferring business class, Rupani opted for economy this time to accompany the families of his close friends, Nitin Bhardwaj and Dhansukh Bhanderi.
The disastrous crash occurred on June 12, when a Boeing 787-8 Dreamliner en route to London went down moments after takeoff from Sardar Vallabhbhai Patel International Airport. Of the 242 individuals on board, 241 lost their lives. Rupani, aged 68, was among the victims. The only survivor was 34-year-old Vishwas Kumar, originally from Vadodara and now a British citizen. The aircraft crashed into a building on the BJ Medical College campus in Meghaninagar, just over a kilometer from the runway.
A massive explosion ensued, engulfing part of the hostel in flames. Among the victims were several MBBS students residing in the building.
Point of View
The operations at the Forensic Science Laboratory highlight the critical role of forensic science in crisis management. The dedication and expertise of the FSL team are commendable, ensuring that victims' identities are confirmed with precision. The ongoing efforts not only showcase technological advancements but also emphasize the humane aspect of forensic work, bringing solace to families in distress.

Frequently Asked Questions
What is the role of DNA profiling in victim identification?
DNA profiling plays a crucial role in victim identification by matching DNA samples from victims with those of their relatives, ensuring accurate identification.
How does the FSL process DNA samples?
The FSL processes DNA samples by using specialized techniques to extract DNA from blood, bones, or teeth, followed by quality analysis and sequencing.
What happens if DNA alleles are not detected?
If sufficient DNA alleles are not detected, the entire identification process must be restarted to ensure accuracy.
How long does the DNA profiling process take?
The DNA profiling process can vary in duration, but FSL is working around the clock to expedite the identification of victims.
What was the outcome of the DNA testing for Vijay Rupani?
DNA testing confirmed the identity of former Chief Minister Vijay Rupani three days after the plane crash.
