The Pune Lohagad Fort murder case could ultimately hinge on a few crucial feet of rock—the spot from which 26-year-old Ketan Agarwal fell to his death on June 18.
Over the past three weeks, what was initially considered a trekking accident has evolved into a high-profile murder investigation. Ketan, a young businessman who was soon to be married, died under suspicious circumstances. His fiancée, 20-year-old Siya Goyal, and her alleged boyfriend, 22-year-old Chetan Chaudhary, have since been arrested. According to the Pune Rural Police, the two conspired to murder Ketan by pushing him off a cliff at Lohagad Fort.
Through official statements and media briefings, investigators have presented their theory that Siya, unhappy with her arranged engagement to Ketan and involved in a relationship with Chetan, plotted the murder with her boyfriend. Police claim the conspiracy included meetings at cafés, rehearsals, and even an earlier failed attempt to carry out the crime.
However, these remain allegations. Neither Siya Goyal nor Chetan Chaudhary has been found guilty, and the charges against them have yet to be proven in court.
For a conviction, prosecutors must establish that Ketan's death was not the result of an accidental fall, a loss of balance, or suicide, but that he was intentionally pushed. While the alleged affair may suggest a motive, and the reported café meetings and rehearsals may indicate planning, investigators must still prove that these circumstances directly led to the alleged murder. Evidence such as phone records, clothing, CCTV footage, location data, and the accused's conduct after the incident may strengthen the prosecution's case, but they must collectively point to only one conclusion.
This is a far more demanding legal standard than simply making allegations, and the Pune Police appear to acknowledge that challenge. In a plea seeking permission for lie-detector tests—which was later withdrawn—the police reportedly admitted before the court that they lacked both a direct eyewitness and conclusive evidence identifying who pushed Ketan. According to reports, the investigators primarily relied on alleged confessions made by Siya and Chetan.
Senior advocate Tanveer Ahmed Mir, who represented Rajesh and Nupur Talwar in the appeal that led to their acquittal in the 2008 Aarushi-Hemraj double murder case, dismissed confessions made while in police custody as unreliable. He also stressed that public opinion has no place in determining guilt, stating that courts decide cases based solely on legally admissible evidence rather than public sentiment.
The Panchsheel Principles
Indian law does not require eyewitness testimony or video evidence to secure a murder conviction. Courts can convict solely on circumstantial evidence, provided it forms a complete and unbroken chain that establishes guilt beyond reasonable doubt.
According to advocate Mir, every individual circumstance must be independently proved, and together they must eliminate every reasonable alternative explanation. If even one crucial link in the chain is missing, the accused is entitled to the benefit of the doubt.
The legal framework governing circumstantial evidence dates back to the Supreme Court's 1952 judgment in Hanumant v. State of Madhya Pradesh, where the Court cautioned against confusing suspicion with proof.
The principles were later formally articulated in the landmark 1984 judgment Sharad Birdhichand Sarda v. State of Maharashtra. Commonly referred to as the "Panchsheel" principles, they require that every circumstance be fully established, point exclusively toward the guilt of the accused, be conclusive in nature, exclude every other reasonable hypothesis, and collectively form a complete chain that leaves no reasonable possibility of innocence.
Mir describes this as an "unbreakable chain," explaining that the prosecution cannot rely on a collection of suspicious circumstances alone. Instead, every significant fact must be conclusively established and logically connected to the next.
Lessons from the Aarushi-Hemraj Case
The Aarushi-Hemraj double murder case is often cited as a key example of the importance of circumstantial evidence.
In 2008, 13-year-old Aarushi Talwar and the family's domestic worker, Hemraj Banjade, were found murdered in their Noida residence. Aarushi's parents, Rajesh and Nupur Talwar, were convicted by a trial court in 2013 but acquitted by the Allahabad High Court in 2017. Tanveer Ahmed Mir represented them during the appeal.
By the time the case reached the High Court, it had attracted nationwide attention, much like the Lohagad case today. The trial court convicted the Talwars based on circumstantial evidence, but the High Court found that the prosecution had failed to satisfy the Panchsheel principles.
One major weakness identified by the defence was the prosecution's inability to conclusively establish that no outsider could have entered the Talwars' home on the night of the murders. The defence also questioned whether the injuries could have been inflicted using a dental scalpel allegedly linked to Rajesh Talwar.
More significantly, Mir presented an alternative theory suggesting that Krishna Thadarai, Rajesh Talwar's compounder and an earlier suspect, could have committed the murders. The defence was not required to prove this theory beyond doubt; it merely needed to establish a plausible alternative explanation sufficient to create reasonable doubt.
What Lies Ahead in the Pune Case?
The Pune Rural Police must now translate every claim made during the investigation into evidence capable of withstanding judicial scrutiny.
Investigators will need to establish that Siya's alleged dissatisfaction with her engagement provided a motive, while her alleged relationship with Chetan, their reported meetings, and the alleged rehearsals demonstrate a criminal conspiracy. Digital evidence—including phone records, chat histories, CCTV footage, and location data—must support the existence of a coordinated murder plan rather than merely suspicious behaviour.
The actions of Siya and Chetan immediately after Ketan's fall are also likely to come under close examination. Investigators may seek to determine whether they attempted to rescue him, raised an alarm, remained at the scene, withheld information from his family, concealed evidence, deleted conversations, or switched off their phones.
Even if these circumstances are established, they would only strengthen the prosecution's chain of evidence. Motive alone does not prove murder. Planning alone does not establish that the act occurred. Nor does allegedly misleading investigators after the incident conclusively prove guilt.
The most critical question remains the fall itself.
According to Mir, the precise location from which Ketan fell could become one of the most significant aspects of the trial. Factors such as the terrain, the cliff's edge, the approach to the spot, Ketan's footwear, the trajectory of his fall, the nature of his injuries, and whether an accidental slip was physically possible will all be carefully examined.
The central legal issue is straightforward: did Ketan fall accidentally, or was he deliberately pushed? If he was pushed, investigators must also establish whether the act was intentional or whether it could have occurred during a physical altercation.
These possibilities remain hypothetical, and that is precisely what the prosecution must address. To secure a conviction, it must eliminate every reasonable explanation other than intentional murder.
Ultimately, the case may come down to reconstructing what happened on those few feet of rock at Lohagad Fort. While public opinion may already have formed its conclusions, the court will require evidence—not assumptions—to determine what truly happened.
