Sister Abhaya's body was found in the well of the St Pius convent on March 27, 1992. The local police and crime branch investigated the case and had concluded that it was a case of suicide.
The CBI took over the case on March 29, 2003, and filed three closure reports, saying though it was a case of murder, the suspects could not be found. The High Court refused to accept the report and asked the probe agency to further investigate.
