A tribal woman and her son died after consuming poison at a village in Odisha's Malkangiri district on Saturday, police said.
Her another son is critical.
Thirty two-year-old Muke Padiami, whose husband died three years ago, lived with her eight year-old son Debendra and six-year-old son Munna at Telerai village.
The widow is suspected to have given some poisonous substance to her sons before consuming it, an officer at MV-79 police station said.
Neighbours rushed the trio to Kalimela hospital, where doctors declared Padiami and Munna as dead while Debendra's condition is serious, MV-79 inspector in-charge Mamata Panigrahi said.
While police suspect that poverty might have driven Padiami to take the extreme step, they are investigating the case.
