An elderly couple from Kerala was found dead at their house in Bhopal, Madhya Pradesh on Friday, with their throats slit.
The deceased have been identified as Gopalakrishnan Nair, 74, a retired Air Force officer, and his wife, 62-year-old Gomathi.
They belonged to Mundarath house at Nayyadipara, Kottapuram in Mannarkad.
Bhopal Deputy Inspector General (DIG) Dharmendra Choudhry said the couple were found dead by their neighbours at their Narmada Green Valley residence.
He added that it was the maid who informed the neighbours after her repeated knocks on the door went unanswered.
“Neighbours who peeped in from a window saw the couple lying in a pool of blood. Their throats had been slit with a sharp object,” the officer said.
While valuables and household goods were intact, police said they were looking at personal enmity as a possible cause.
A reward of Rs 20,000 has been announced for any information on the case and a team led by the local Superintendent of Police has been formed to solve it, the officer said.
The couple is survived by their three daughters who are married.
The cremation will be held in Bhopal at 12.30 pm on Saturday.
An investigation is underway into the incident.
