Police said Shivakumar, employed in Qatar had come to his native place a few days ago to celebrate Diwali with his wife.
The couple have a two-year-old baby.
They said some persons had entered the house this morning and stabbed Shivakumar and his wife, who died on the spot.
The man collapsed but still managed to call for an ambulance. However he died en route to the hospital.
Police said they are ascertaining whether Shivakumar was killed over a monetary dispute as he had lent money to some villagers or if it was a fallout of having tried to be a mediator in a property matter in his wife's house.
