Kolkata: Sanjay Roy remains the only accused person on paper in the past 30 days of probe into the rape and murder of the RG Kar Hospital doctor – initially by the Kolkata Police and then by the CBI. The central investigating agency has, meanwhile, interrogated almost 100 witnesses and ran 12 polygraph tests.
Roy was arrested by the Kolkata Police on Aug 10 – a day after the incident. While Roy has claimed he is being framed in the case, the CBI considers him the prime suspect. The 33-year-old suspect, who was first spotted in the CCTV grab at the hospital, was tracked after his Bluetooth earphone was found near the body of the victim on the third-floor seminar hall in the emergency building. Kolkata Police’s investigation led the sleuths to believe that the woman was gagged and that there were multiple signs of injuries on her body. She was allegedly strangled and her thyroid cartilage broke because of it.
Roy, who was seen entering the hospital at 4 am on Aug 9, was seen exiting the building after 40 minutes. His earphone was missing and the device later paired with his cellphone. Later, traces of blood and skin found under the victim’s fingernails matched Roy’s DNA. After CBI took over the probe, Kolkata Police handed over 53 items seized by them, including Roy’s clothes and undergarments. The CBI primarily ran Roy through a series of investigations by psychology experts, who termed him a “sexual pervert” with “animal-like instincts”. The agency, which has sent his DNA and forensic reports to AIIMS Delhi, is awaiting its final opinion on that.Meanwhile, Roy has claimed before the additional chief judicial magistrate that he is being framed. During the polygraph test, he was asked what his next act was after committing the murder. Roy interrupted at this point and claimed that he had not committed the murder and such a question does not arise. He said that he had entered the room and found the woman lying unconscious and covered in blood. Roy claimed that he did not even know her, although CCTV grabs from the night of Aug 8 have shown him staring at the woman.
The CBI has also spoken to nearly 100 witnesses, including the hospital’s security staff, doctors, nurses and the victim’s friends. Witnesses, including former RG Kar Medical College and Hospital principal Sandip Ghosh and Roy’s friend Anup Dutta – an ASI with Kolkata Police – were run through polygraph tests. CBI also spoke to the victim’s friends and recorded the statements of her parents. They also ran some of them through the Deception Detection Tests (DDT). On Sept 6, the ACJM court remanded Roy to 14 days’ judicial custody.
