The investigation into the alleged murder of Ketan Agarwal at Pune’s Lohagad Fort has entered a critical phase, with police relying on scientific evidence and circumstantial proof instead of eyewitness testimony. Investigators recently recreated the crime scene with the two accused, Siya Goyal and her alleged lover Chetan Chaudhary, while also carrying out a forensic gait analysis that is expected to play a significant role during the trial.
Pune police are relying on crime scene recreation and forensic gait analysis at Lohagad Fort for the alleged Ketan Agarwal murder investigation, focusing on circumstantial evidence against Siya Goyal and Chetan Chaudhary due to lack of witnesses.
Crime Scene Recreation And Gait Analysis Underway
Police took Chetan Chaudhary to Lohagad Fort early on Wednesday under tight security, with more than 25 officers present during the reconstruction exercise. Siya Goyal had been brought to the same location a day earlier for a similar procedure.
According to experts, recreating the crime scene allows investigators to demonstrate before the court how the alleged offence was committed. The exercise records details such as the victim’s position, the movements of the accused and the sequence of events leading to the death. These reconstructions are documented through video recordings and witnessed by independent observers.
Experts also highlighted the importance of gait analysis in the case.
“Gait analysis is performed to establish that the accused was present at the scene on the day of the murder. The accused is taken to the location, and a scientific record is created regarding their gait (walking style), facial expressions, body language, height, and the length of their limbs.”
They added, “Records from forensic gait analysis are difficult to challenge in court because they serve as evidence proving the accused’s presence at the crime scene.”
Supreme Court’s ‘Panchsheel’ Principles Come Into Focus
With no eyewitness to the alleged murder, the prosecution is expected to rely heavily on the legal principles laid down by the Supreme Court in the 1984 Sharad Birdhichand Sarda vs State of Maharashtra judgment. The ruling clarified that a conviction can be based entirely on circumstantial evidence, provided five stringent conditions, popularly known as the ‘Five Golden Principles’ or ‘Panchsheel’, are satisfied.
The five principles require that:
- Every circumstance presented against the accused must be conclusively proved.
- All established facts should point only towards the guilt of the accused.
- The evidence must be firm, consistent and beyond doubt.
- Every reasonable possibility of innocence must be ruled out.
- The chain of evidence should be complete and lead to only one conclusion that the accused committed the crime.
Investigation Hinges On An Unbroken Chain Of Evidence
Legal experts believe the investigation into Ketan Agarwal’s death will be judged against these five principles. Since there are no direct witnesses, investigators must establish every link in the sequence of events through scientific and circumstantial evidence.
“The police do not have any eyewitnesses to the incident. Therefore, the scene recreation and gait analysis conducted at Lohagad represent an attempt to scientifically establish these ‘circumstances’ before the court. The police must prove in court that the sequence of events – Chetan and Siya leaving home, arriving at Lohagad, the incident itself, and the subsequent circumstances – forms an ‘unbroken chain’ that directly establishes them as the killers,” an expert said.
Even One Missing Link Could Weaken The Case
Experts cautioned that the prosecution’s case depends on maintaining a complete chain of evidence. If any crucial link fails to withstand legal scrutiny, the defence could use it to challenge the allegations.
“If there is even a 1% logical possibility of the accused being innocent, they will be entitled to the ‘benefit of the doubt’ and could be acquitted,” the expert explained.
As the investigation progresses, the reconstruction of the crime scene and forensic gait analysis are expected to be key elements in determining whether the prosecution can satisfy the Supreme Court’s strict standards for convictions based solely on circumstantial evidence.
