Why Police Want to Give Siya Goyal a Polygraph Test in Ketan Agarwal Murder Case
Indiadailyupdate.com – In the ongoing investigation into the Ketan Agarwal murder case, the police have announced their intention to administer a polygraph test to Siya Goyal, the accused’s sister. This decision comes amid a lack of conclusive evidence, with authorities aiming to extract truthful responses about her alleged role in the crime. The polygraph, often referred to as a lie detector, is being considered as a means to resolve lingering doubts and strengthen the case against Siya and her co-accused, Chetan Choudhary.
The Role of Polygraph Tests in Criminal Investigations
Polygraph tests are widely used in forensic investigations to assess the truthfulness of a subject’s responses. However, their reliability remains a topic of debate, as they measure physiological responses rather than directly proving guilt. In the Ketan Agarwal case, the police are relying on this tool to corroborate or challenge testimonies, particularly those from Siya Goyal’s family and social circle. The test is expected to focus on her knowledge of Ketan’s death, her relationship with the accused, and any possible motive for the crime.
Siya Goyal’s brother, Sahil Goyal, has provided a key statement to the inquiry, asserting that she was “eagerly anticipating her wedding and actively participated in all pre-wedding arrangements.” This narrative directly contradicts the police’s claim that she pushed Ketan off a cliff to delay the marriage. The discrepancy highlights the need for additional evidence to bridge the gap between Siya’s account and the allegations against her. The polygraph test is viewed as a critical step in resolving these contradictions and clarifying the sequence of events.
Challenges in Building a Conviction
Without direct evidence such as CCTV footage or eyewitness testimony, the investigation has relied heavily on circumstantial clues and digital data. Forensic experts are analyzing mobile records, deleted messages, and location information to trace the movements of Siya Goyal and Chetan Choudhary around the time of Ketan’s death. The police also emphasize family statements and available video evidence as crucial components of their case. These elements, however, require careful interpretation to form a cohesive timeline and establish clear motives.
Experts argue that polygraph results should not be treated as definitive proof in legal proceedings. While the test can highlight inconsistencies in a person’s responses, it does not eliminate the possibility of deception. In India, the use of polygraph findings is often supplementary, with courts requiring corroborating evidence to validate its conclusions. This context underscores the significance of the test as a tool to narrow down suspects and strengthen the case, rather than serve as a standalone proof of guilt.
Public and media attention to the case has intensified, with many questioning whether the polygraph test is a necessary step or a last-ditch effort to secure a conviction. Legal analysts have pointed out that the test could provide valuable insights, but its success depends on the subject’s ability to remain calm and truthful during the process. The police are also expected to present new findings from digital forensics to complement the polygraph results, ensuring a comprehensive approach to the investigation.
