Former media baron Peter Mukerjea, an accused in the Sheena Bora murder case, was Saturday subjected to a polygraph test by the CBI to “verify” his statements. CBI sources claimed that the test became necessary as Peter purportedly changed his version a number of times on key aspects of the murder mystery and his answers were not convincing.
Peter, 60, was taken to the Central Forensic Science Laboratory (CFSL) Saturday morning for questioning. Sources said only scientists and Peter were present in the room when the test was carried out. The list of questions was handed over to the CFSL expert who carried out the examination.
The sources claimed that some answers indicated deception but no inference can be drawn as of now because the report is yet to be submitted to the agency. They said whether Peter was deceptive or not can only be ascertained after the agency receives a complete report from the CFSL.
CBI sources said several questions about the crime, his conversations with his wife Indrani Mukerjea and his own statements were put to him during the test. “A change in a person’s consciously-held feelings produces a psychological defence reaction in the form of physiological changes in his blood pressure, pulse rate, respiration and electrodermal response,” the CBI claimed.
It said fear of detection and entrapment induces a person to conceal the facts and this produces uncontrollable physiological reactions, which are precisely measured by the polygraph machine.
The CBI received the nod from a special court to subject Peter to the lie-detector test. The agency will have to produce him on Monday before a special court in Mumbai which has given it his custody.
The agency has subjected Peter to intense questioning since November 19 when he was taken into custody. The questions related to alleged siphoning off funds from the media house founded by him and Indrani, overseas account of Sheena Bora, relations between family members, missing details of Sheena and his conversations with son Rahul.
