The two were missing from the village for about a week and their bodies were found hanging by villagers this morning with the woman's one-and-a-half-year-old son crying at the site, said inspector-in charge of Aska police station, Baleswara Gidhi.
The woman was identified as Bishnupriya Behera and her nephew Madana Behera (25), residents of Karpura Nuagaon under the Aska police station limits, the police said.
The bodies have been sent for postmortem and investigation was on to ascertain the circumstances that led the duo to the extreme step, they said.
