Ram Sewak (60) and his wife Katori Devi (58) were killed by a sharp-edged weapon late last night, SSP Rajesh D Modhak said.
As the couple was not having cordial relationship with their two widowed daughters-in-law they were living separately in a hut on their agricultural field where the incident took place, the SSP said.
A dispute over Ram Sewak's agricultural land was going on, the SP said.
