The psychoanalytic profile of the arrested accused in the rape and murder of the woman doctor at the state-run RG Kar Medical College and Hospital, Sanjay Roy, indicated that he was a pervert and severely addicted to pornography, a Central Bureau of Investigation (CBI) officer said on Thursday.
Quoting the doctors from New Delhi's Central Forensic Science Laboratory (CFSL), the officer also said that the civic volunteer of the Kolkata Police has an 'animal-like instinct'.
The body of the post-graduate trainee was found in the seminar room of the hospital on August 9.
The civic volunteer was arrested the next day in this connection.
"The man showed no repentance and narrated the entire episode giving every minute detail without hiccups. It appeared that he had no remorse," the official of the central probe agency told PTI on Thursday.
Several pornographic contents were found in the mobile phone that Roy was using and later seized by the Kolkata Police before the investigation was handed over to the CBI on an order of the Calcutta high court.
The CBI officer said that pieces of evidence, both technical and scientific, 'very much support' that the accused was present at the crime scene.
Referring to the CCTV footage collected from the hospital, he said, Roy could be seen near the chest department ward at around 11 am on August 8.
"Footage showed him entering the same building again at around 4 am on August 9. Certain technical and scientific evidence corroborated that," he said.
The officer did not want to divulge anything about the DNA tests conducted on Roy.
He also refused to comment on the ongoing buzz that there was no gangrape in this case.
The CBI officers have visited Roy's residence in Bhowanipore, spoke to his family members, neighbours and also to his colleagues in the Kolkata Police force.
