Peter Mukerjea takes polygraph test

CBI sources claimed that the test became necessary as Mukerjea purportedly changed his versions number of times on key aspects of the murder mystery and his answers were not convincing. 60-year-old Mukerjea was taken to the Central Forensic Science Laboratory on Saturday for questioning. They said only the scientist and Mukerjea were present in the room when the test happened.

The list of questions on which Mukerjea was tested were 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 report is yet to be submitted to the agency. They said whether Mukerjea 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. The agency will have to produce Peter on Monday before a special court in Mumbai which has given it his custody.

CBI has subjected Mukerjea to intense questioning since November 19. The agency confronted Peter with the Income Tax returns filed by him and Indrani to ascertain their various investments.

The sources, however, clarified that at this stage it is difficult to nail any one possible motive behind Sheena’s murder and the agency is working on different angles.
