Kolkata Doctor Case: A Glance

The Kolkata Doctor Case shocked the entire city. On August 9, 2024, someone raped and murdered a trainee doctor at RG Kar Medical College and Hospital. The Kolkata Rape and Murder Case drew swift and intense attention from authorities and the public.

Sanjay Roy’s Statement in Court

Sanjay Roy stood in court and insisted on his innocence. He said he did not commit the crime and requested a polygraph test to prove his claim. The court approved the test and placed him in judicial custody for 14 days. Sanjay Roy hopes this test will clear his name.

What is Polygraph Test?

A polygraph test, commonly known as a lie detector test, is a procedure used to measure and record various physiological indicators—such as blood pressure, pulse, respiration, and skin conductivity—while a person answers a series of questions.
The idea behind the test is that deceptive answers will produce physiological responses that can be differentiated from those associated with non-deceptive answers.

How Polygraph Test Works?

1. Baseline Establishment: The test begins by asking simple, non-threatening questions to establish the person’s baseline physiological responses.
2. Questioning: The examiner then asks a series of questions relevant to the investigation, mixed with control questions that are unrelated to the case. The responses to these questions are monitored and recorded.
3. Analysis: The polygraph examiner analyzes the physiological responses to determine if there are significant changes when the person answers the relevant questions. These changes might indicate stress or anxiety associated with lying.

Limitations of Polygraph Test –

While the polygraph can detect signs of stress, it is not foolproof and is subject to criticism for its accuracy. Stress or anxiety can be triggered by factors other than lying, and some individuals may be able to control their physiological responses even when lying.

In many jurisdictions, polygraph test results are not admissible as evidence in court due to concerns about their reliability. However, they are sometimes used during investigations or in employment screenings.

When Was Sanjay Roy Arrested?

Police arrested Sanjay Roy on August 10, 2024, just one day after the crime. Surveillance footage showed him entering the building at the time of the incident, directly linking him to the Kolkata Rape and Murder Case.

Evidence Against Sanjay Roy

More Suspects in the Case

The investigation into the Kolkata Rape and Murder Case extends beyond Sanjay Roy. The court allowed polygraph tests for other suspects, including the former principal of RG Kar Medical College and four doctors who spent time with the victim on the night of the incident. Investigators are thoroughly examining these individuals as they work to uncover the full truth in the Kolkata Doctor Case.
