NPR's Julie McCarthy reports today on another alleged gang rape and murder in India — this one involving two teenage sisters from the lowest Hindu caste whose bodies were found hanging from a mango tree.

Julie says the two girls, ages 14 and 15, were killed in a village about 140 miles east of the capital New Delhi.

"They reportedly had gone to a field to relieve themselves but never returned," Julie says. "Like hundreds of millions of Indians, they lacked a bathroom at home."

The girls' family belong to the Dalit caste, formerly known as "untouchables," the lowest rung of India's ancient system of societal hierarchy.

The Press Trust of India says charges have been filed against seven people, including two police constables. Local media report that one of the policemen allegedly participated in the attack. The other is said to have refused to listen to relatives who reported the two girls missing.

The Associated Press says: "Hundreds of angry villagers stayed next to the tree throughout Wednesday, silently protesting the police response. Indian TV footage showed the villagers sitting under the girls' bodies as they swung in the wind, and preventing authorities from taking them down until the suspects were arrested."
