What was initially reported as a tragic fire accident inside a Life Insurance Corporation (LIC) office in Madurai has now been revealed as a cold-blooded murder, police said on Tuesday. A month after senior branch manager A Kalyani Nambi, 54, was found charred to death in her office cabin, investigators arrested her colleague, assistant administrative officer D Ram, 46, accusing him of killing her and attempting to destroy crucial documents to erase evidence.

The incident took place on the night of December 17 at the LIC building on West Veli Street, a densely populated commercial stretch in the city. Ram, who also sustained burn injuries, had initially claimed that a masked intruder entered the office, attempted to rob Kalyani of her jewellery, and set the building on fire before fleeing. That version, police said, began to fall apart under scrutiny.

Clues point to murder, not accident

Investigators said Ram’s statements during questioning were riddled with contradictions. Suspicion deepened after police recovered plastic bottles filled with petrol from his office cabin, along with a pipe allegedly used to siphon fuel from his motorcycle. The turning point came when Kalyani’s son informed officers that his mother had called him shortly before her death, urging him to alert the police, indicating that she feared an immediate threat.

These findings prompted authorities to reclassify the case from an accidental fire to a suspected homicide. Further investigation revealed simmering workplace tensions between the two colleagues, police said.

Professional conflict and a staged crime

According to investigators, the motive stemmed from disputes over delayed insurance claims. Several agents had reportedly complained to Kalyani that Ram had been holding back more than 40 death claim files for a prolonged period. When Kalyani confronted him and warned of escalating the issue to senior officials, police believe Ram decided to eliminate her and destroy the documents.

Police reconstruction suggests the crime was carefully planned. Around 8.30 pm, Ram allegedly disconnected the main power supply to the building and sent an email to the Tamil Nadu Electricity Board reporting a fault. He then chained the glass entrance to restrict access. When the power went out, Kalyani reportedly noticed someone attempting to lock the door and raised an alarm. Investigators say Ram then entered her cabin, doused her with petrol and set her ablaze, leaving her trapped. He allegedly set fire to his own cabin afterward to make the incident appear accidental, suffering burns in the process.

Following sustained interrogation, police said Ram confessed to the crime. He was arrested late Monday night from his residence and admitted to Government Rajaji Hospital for treatment. The case, originally registered as an accidental fire, has now been amended to include charges of murder, destruction of evidence, failure to report an offence and providing false information under the Bharatiya Nyaya Sanhita, along with provisions of the Tamil Nadu Public Property (Prevention of Destruction and Loss) Act.

Police said the investigation is ongoing, with a detailed review of the destroyed files and Ram’s role in the pending insurance claims still underway.
