Budhni Tirkey who stayed with her three orphan grand daughters was threatened by several youths last evening to leave the area as they blamed her for the recent deaths in the area.
Later the youths returned in the night and forcibly took away Budhni, whose grandaughters lodged a complaint with the police.
Her badly wounded body was found today near Dooars railway line in Malbazar, the police said.
None was arrested and investigation into the abduction and killing was on, the police added.
Budhni's grand daughters said a number of people had died of chikunguniya, malaria and malnutrition recently.
Most of the tribal families in the area are so poor that they do not have money to access medical facilities.
