The Secret Lexicon: Coded Chats and the Logic of a Pune Murder Mystery

As Siya Goyal and Chetan Chaudhary head to judicial custody, investigators are decoding a trail of encrypted messages that may reveal the final moments at Lohagad Fort.

The investigation into the tragic death of Ketan at Lohagad Fort has shifted from a search for motive to the decryption of a digital shadow. Pune police, working to piece together the events that led to a 400-foot fall, have uncovered a series of chats between the primary suspects, Siya Goyal and Chetan Chaudhary, conducted entirely in coded language and nicknames. This discovery has turned the case into a high-stakes puzzle, with investigators now scrutinizing a second mobile phone seized from Goyal to find the key to this private lexicon.

A Web of Codes and Re-enactments

The prosecution’s request for an extended police remand was anchored in this specific evidence—digital logs that suggest a premeditated plan hidden behind seemingly innocuous exchanges. While defence lawyers successfully argued against further detention, leading to a 14-day judicial custody order from a Pune court, the technical nature of the evidence remains central. Beyond the digital trails, the police have adopted a forensic approach, including a recent on-site re-enactment at the fort using a dummy to verify the physical dynamics of the fall.

The investigation has also drawn from a broad spectrum of reporting, with outlets like AajTak highlighting the importance of the crime scene reconstruction, while Asianet News Hindi has brought forward testimonies from guards at the ticket counter, hinting at a wider conspiracy. These fragments of information, once disparate, are now being stitched together to build a narrative of calculated intent rather than an accidental tragedy.

The Polygraph Factor

A significant breakthrough occurred when Goyal consented to a polygraph test, a procedure that relies on physiological responses—heart rate, blood pressure, and skin conductance—to gauge the veracity of her statements. In a case where the primary suspects have maintained a wall of silence, such forensic interventions are often the final bridge to the truth. Whether this leads to a confession or merely highlights inconsistencies in their timeline remains to be seen.

Why It Matters: The Digital Trail

This case marks a grim trend in modern criminal investigations: the transition from physical evidence to digital forensics. In the age of encrypted communication, the "code" is the new weapon. For investigators, the challenge lies not just in finding the suspect, but in interpreting the context of their private language. As reporting from journalists like Madan Tiwari suggests, the reliance on these hidden chats indicates that the accused expected their digital presence to be a primary battleground for law enforcement. If the police can break these codes, it will provide more than just evidence—it will provide the blueprint of the crime itself.
