The polygraph test of a total of seven people has started in the case of rape and murder of a female trainee doctor at RG Kar Medical College Hospital. The polygraph test of accused Sanjay Roy, former principal of RG Kar Medical College Dr. Sandeep Ghosh, four doctors who were with the victim on the night of the incident and a volunteer is being conducted at the Kolkata office of the CBI.
Why does the CBI want a polygraph test?
The CBI aims to verify the statements of these employees, as other medical reports (such as DNA taken from the victim’s body, vaginal swab, PM blood) have failed to clearly link them to the incident. The CBI wants to know whether these four had tampered with evidence in any way or were part of any conspiracy.
