A woman poisoned her two minor sons and then committed suicide at Telrai village under Kalimela block under the MV 79 police station in the district on Saturday.
While Muka Padiami and one of her sons died on the spot, the other son was battling for his life at a hospital in Kalimela.
The woman was staying with her in-laws after her husband died of leprosy three years ago. On Friday night, there was a bitter quarrel between Muka and her in-laws over some family matter. On Saturday morning, she served pesticide-laced soft drink to her sons and later drank it.
Locals rushed three of them to the Kalimela hospital, where Muka and one of her sons were declared dead.
The woman might have taken the extreme step due family feud, said Telrai Sarpanch Muta Sodhi. The Kalimela police are investigating into the incident.
