Superindent of Police Ashok Mishra said that the bodies of Jagadananda Panda, 50 and those of his wife, father and two sisters were found with bullet injuries in Deogaon.
Police also said, "The incident, which took place in the wee hours, appeared to be a case of suicide as Panda's service revolver was found at the site and main door and other entry points were found closed."
Panda was Protector General of Emigrants. He was special relief commissioner in Orissa before going on Central deputation a few years ago.
The bodies have been sent for post-mortem and investigations are on into the matter. While, his 22-year-old son who was critically injured has been admitted to a hospital.
