A 28-year-old woman on Wednesday poisoned her daughters, killing them before ending her life in Mudimyala village of Chevella in Ranga Reddy district, the police said on Thursday.

Narsimha found the bodies of his wife G. Shobha Rani and their two daughters, Spandana, 5, and Meena, 2, in their house on Wednesday night.

“Narsimha used to harass his wife by returning home drunk and beat her up,” Chevella Sub-Inspector E. Shekhar said. After a similar incident on Wednesday, Rani administered poison to the kids and later consumed it herself, Mr. Shekhar said.
