For weeks after he was arrested, Raman refused to answer any questions. He remained silent and said that no torture methods would be successful on him. Of all the tricks in the book, it was a chicken dish that made Raman talk. While in the lock-up, Raman requested Chicken curry. After weeks of interrogating him, the police decided to give in to his request. After finishing his chicken curry, Raman invited the officers to ask him whatever they wished to ask. It took fulfilling a few more wishes before the police got to know everything they wanted. Raman confessed to committing 41 murders. Post his confession, he took the police force on a citywide tour to show the places he operated in and to obtain the rod he had hid in the northern suburbs. The accused was therefore sent to the Police Surgeon, Mumbai, who observed him from 28 June 1969 to 23 July 1969 and opined that,"The accused is neither suffering from psychosis nor mentally retarded. His memory is sound, his intelligence average and is aware of the nature and purpose of his acts.
