Kolkata Rape-Murder: DNA, Forensic Reports Show Only Sanjay Roy’s Involvement, CBI To Seek AIIMS Opinion

With the DNA and forensic reports indicating only arrested accused Sanjay Roy’s involvement in the rape and murder of a trainee doctor at Kolkata’s RG Kar Medical College and Hospital on August 9, the Central Bureau of Investigation (CBI) will consult All India Institute Of Medical Sciences (AIIMS) experts for a final opinion.

Sources told CNN-News18 that so far there is no evidence to suggest involvement of any other person in the rape and murder.

“The CBI wants to rule out any lacuna, so AIIMS experts will be asked for a final opinion on the DNA and forensic reports," the source said.

The family of the victim had suspected gang rape. However, on Tuesday, ruling Trinamool Congress (TMC) MP Mahua Moitra posted on X: “It wasn’t gangrape, there was no fracture, no hurried cremation and autopsy was videographed. Killer was caught within 12 hours and the CBI is charge of the case."

‘POLYGRAPH TEST GAVE NO LEADS ON INVOLVEMENT OF OTHERS’

The polygraph test conducted on Roy, ex-principal of RG Kar Sandip Ghosh and five others have also not given any leads to the CBI about the role of any other individual, as per officials in the know.

Sources told CNN-News18 that Roy’s polygraph test focused on trying to ascertain if anyone else accompanied him to the seminar hall of R G Kar’s chest department, when the crime was committed.

Roy has been captured on CCTV entering RG Kar alone at 4.03 am on August 9. “Polygraph test answers are usually in yes or no. Body parameters are analysed by experts to ascertain if a person is lying. The forensic team put questions to Roy if anyone else colluded with him. The answers were in the negative," an official involved in the probe told CNN-News18.

Officials added that although polygraph is not admissible evidence, the decision to carry out the test on Roy was taken to look for any possible leads that he may not have provided to police or the CBI during the sustained interrogation.

‘ACCUSED SOLICITED SEX BEFORE THE CRIME’

Officials said the questioning of civic volunteer Saurabh Bhattacharya and corroborative evidence show that Roy solicited sex before the crime.

Bhattacarya in his statement to the CBI has allegedly said that Roy accompanied him to two red-light areas — Sonagachi and Chetla — on August 8. He also allegedly solicited sex from two women.

One of the two women “is an official known to Roy", while the second is a married woman whom Roy refers to as his girlfriend, said officials.

The statements of the two women have also been recorded by the investigators. Roy’s mobile phone records and his mobile tower location are crucial corroborative evidence in this regard, officials said.
