In a ground-breaking achievement, Kerala Police have successfully solved a mystifying 19-year-old murder case, utilizing cutting-edge Artificial Intelligence (AI) technology to track down two long-evading suspects involved in the brutal killings of a woman and her twin newborns in Kerala, India.

 

The chilling crime took place on February 10, 2006, in Anchal, a town in Kerala’s Kollam district. Santhamma returned from the Panchayat office to a horrific sight—her daughter Ranjini and her 17-day-old twin daughters had been murdered, their throats slit.

 

Initially, the police identified two suspects: Divil Kumar and Rajesh, both army personnel then stationed at the Pathankot military base. Despite intense efforts, the suspects eluded capture, and the case gradually went cold over time.

 

The Breakthrough

In 2023, Kerala Police’s Technical Intelligence Wing revisited the case with a fresh perspective, turning to AI to unlock new leads. AI technology was employed to enhance old photographs of the accused, generating digital age-progressed images to predict what the suspects might look like after almost two decades.

 

This innovative approach led to a crucial breakthrough: a wedding photograph shared on social media displayed a man who bore a striking 90% resemblance to one of the suspects. The individual in the photo was identified as "Praveen Kumar" from Puducherry, and upon further investigation, it was confirmed that he was indeed Rajesh. This discovery set the wheels in motion, ultimately leading to the identification of Divil Kumar, now living under the alias “Vishnu.”

 

On January 4, 2025, after nearly two decades, both suspects were arrested in Puducherry by the Central Bureau of Investigation (CBI). It was revealed that the two had assumed new identities and were working as interior designers.

 

The Crime and Motive
The investigation revealed that Ranjini and Divil were once in a relationship but had grown apart after she informed him about her pregnancy. Divil distanced himself and moved to Pathankot, but Ranjini decided to carry the pregnancy to term.

 

In January 2006, Ranjini gave birth to twin daughters in Thiruvananthapuram. Around the same time, Rajesh, posing as “Anil Kumar,” befriended Ranjini and offered emotional support. Rajesh and Divil, who had served together in the army, conspired to murder her.

 

Ranjini, determined to resolve the paternity dispute, approached the State Women’s Commission, which issued an order for Divil to undergo a DNA test. On the day of the crime, Rajesh convinced Ranjini’s mother, Santhamma, to go to the local Panchayat office for official work. While she was away, Rajesh, acting on Divil’s orders, brutally murdered Ranjini and her children.

 

 

Despite the discovery of a two-wheeler registered to the military base at the crime scene, the suspects managed to escape and remained free for nearly 20 years.

 

AI: Revolutionizing Crime Solving
Kerala’s Additional Director General of Police (Law and Order), Manoj Abraham, commended the police technical intelligence team for their innovative use of AI in solving this long-unsolved case. AI played a crucial role in generating age-progressed images of the suspects, which were then cross-checked with social media profiles, leading to their identification.

 

This success story demonstrates the immense potential of AI in modern law enforcement, helping solve cold cases and deliver justice, even after decades. It highlights the Kerala Police’s commitment to embracing technology to fight crime and bring perpetrators to justice, showcasing the power of innovation in the state of Kerala, India.
