Bhule Chauhan (70) and his wife Rani Chauhan (55) were found murdered in their three-storey house in Noida Sector-44, where they lived alone on Saturday morning, police said.
The incident reportedly came to the light around 8:30 am when a local priest reached their house to invite the duo in a religious programme organised at a nearby temple.
After finding their bodies under semi-decomposed condition, the priest informed the local police immediately that reached the spot and took away bodies for autopsy after breaking the door locked from inside.
A senior police official said the couples owned properties worth crores, including three houses and valuable lands in posh sectors of Noida. Police suspect that they might have been killed by some known person over alleged undertaking of their properties.
Superintendent of police, Noida, Dinesh Yadav said the couples were attacked by blunt objects on their head and police are investigating the case from all angles.
Also, Inspector General (Meerut Range) Ajay Aanad, along with senior police officials, inspected the spot.
The deceased had a 21-year-old son Gaurav Chauhan who died five years ago under mysterious circumstances, police said.
After the death of his first wife, Bhule had married another woman, said police, adding that he had a daughter with his first wife who got married with one Krishna of Shapur village but they were not in contact from a long time.
Police said Bhule had two elder brothers who died a few years ago. There is no legal heir of their property and they lived on the rent collected from their properties, said police. Sources said the murder was committed over a matter of property overtake.
"Both of them were seen by the locals last time on Friday around 10 am. We suspected that they were killed on the same day. There was also a friendly entry into the house. The valuables were not ransacked which denies robbery bids,” said some local residents.
"We are questioning a shopkeeper to ascertain the identity of the people who were friendly with the couple. Also, we are questioning their relatives to find out their involvement in this case," the SP said.
An FIR was registered against unknown persons under section 302(murder) of the IPC in sector 39 Police Station.
