The mystery behind the death of IAS officer D K Ravi (IAS:KN2009) deepens with reports coming in that the deceased spoke to one woman IAS officer of his batch. She was the last person to speak before he hanged himself. However, Karnataka CM drew flake for disclosing the fact that Ravi had called up the woman officer 44 times a day before his death. The family of Ravi was not ready to speak to any authority other than the CBI but later on they relented and spoke to CID. But several questions are emanating on suspicious death of an upright officer that only CBI can answer. Unfortunately the Police commissioner, state home minister and even the chief minister had declared it suicide even before post mortem.
