An elderly man was strangled at his house in North Bengaluru's JC Nagar on Sunday.

The victim, Nanjundaswamy (67), was a retired BHEL employee and a resident of Kamalanagar in JC Nagar.

The police suspect that he was murdered between 4 pm and 8 pm but the incident came to light only when his younger brother’s son came to visit him on Sunday. He found Nanjundaswamy lying on the floor. The door was left open, and the television and fan were on, the police said.

The police found strangulation marks on the victim’s neck. They have not recovered any weapon from the crime scene.

The victim’s body was shifted to the Victoria Hospital for post-mortem.

Preliminary investigations revealed that the murder was not committed for gain as cash and other valuables were found intact at the house.

As there was no forced entry, police suspect someone known to the victim committed the crime. They are analysing the victim’s call detail record (CDR).

Inquiries so far revealed Nanjundaswamy had two wives, both of whom are no more. He had a son named Pramod with his first wife, Yashodha. He lived on the first floor while Nanjundaswamy lived on the ground floor, the police said.

The victim’s second wife was Maraka, the police added.

The police are also probing a property dispute angle between stepchildren.

“We are awaiting the post-mortem report to ascertain the cause of death. Looks like the murder was not for gain. We are probing all the possible angles,” said Ravi Channannavar, DCP (West).

The Basaveshwaranagar police registered a case of murder based on a complaint lodged by the victims’ relative, Manjunath.

Further investigations are under way.
