A CBI officer, who wishes to remain anonymous, suggested that the young doctor’s murder might have been planned, based on findings from the second phase of the investigation. Reports indicate that the rosters for the two junior doctors involved were altered on August 7. This change raises questions about the circumstances surrounding the incident. Further inquiries are expected as the investigation unfolds.

In the RG Kar case, Sandeep Ghosh reportedly exchanged photos with two junior doctors from the victim’s department just hours before the murder.
They allegedly communicated through video calls and held a conference call, with around 30 interactions occurring between the afternoon of August 8 and midnight on August 9.

A report from Anandabazar newspaper cites an unnamed CBI officer who suggests that the young doctor’s murder may have been premeditated, as indicated in the second phase of the investigation. It has also come to light that the duty rosters for these junior doctors altered on August 7. The CBI reviewed the duty rosters from previous months but found no prior instances of such abrupt changes.
From the outset of the investigation, there have been assertions of a broader conspiracy behind the murder. Although Abhijit Mandal and Sandeep Ghosh are not named in the charge sheet, the CBI opposed their bail.
The charge sheet only references Sanjoy Roy. The evidence collected by the CBI led to the filing of charges against Sanjoy, but indications suggest the murder may have been premeditated, requiring court-admissible evidence for further action.
The report notes that photos and videos were exchanged between Sandeep and the junior doctors from the afternoon of August 8 through late into the night of August 9.
However, CBI officials are hesitant to disclose the specifics of these exchanges due to ongoing investigations. These details have been included in the status report submitted to the Supreme Court.
Furthermore, the Anandabazar report states that significant information has emerged from analyzing the phones of Sandeep Ghosh and Abhijit Mandal, suggesting that they may soon face questioning. The devices belonging to the two junior doctors from the chest medicine department have also been thoroughly examined.
Sanjay Roy, arrested by the Kolkata Police on August 10, a day after the incident, has claimed he is being falsely accused. However, the CBI considers him the prime suspect in the case.
The 33-year-old suspect was first identified through CCTV footage from the hospital. His Bluetooth earphone, found near the victim’s body in the seminar hall on the third floor of the emergency building, helped police trace him. The victim had multiple injuries and a broken thyroid cartilage, suggesting she had been gagged and strangled. CCTV footage showed Roy entering the hospital at around 4 a.m. on August 9 and leaving approximately 40 minutes later.
Notably, his earphone was missing when he left the building, but it later reconnected with his phone, further linking him to the crime. Forensic evidence, including blood and skin found under the victim’s fingernails, also matched Roy’s DNA, solidifying his involvement.
The trainee doctor’s body discovered on August 9, sparking an investigation that has now culminated in formal charges against Sanjay Roy.
Roy, aged 33, was a civic volunteer with the Kolkata Police at the time of his arrest. The investigation took a significant turn when a Bluetooth device discovered near the victim’s body was traced back to Roy, leading to his immediate apprehension. Further damning evidence included CCTV footage that placed him on the third floor of the hospital, close to the location of the seminar hall where the crime occurred.
In addition to Sanjay Roy, the CBI also conducted polygraph tests on several other individuals connected to the case. According to a report, four people, including Sandip Ghosh, the former principal of RG Kar Medical College and Hospital (RGKMCH), underwent polygraph tests at the CBI’s Kolkata office. The results from these tests are expected to aid the investigators in piecing together the events leading up to the doctor’s tragic death.
