CHENNAI: A 32-year-old woman and her three daughters committed suicide by hanging themselves in their house in Manali on Saturday.

L Lakshmi and her daughters were found dead at 7pm when Lakshmi’s husband Jayaraman returned home. As the house was locked from inside, Jayaraman and the neighbours broke open the door.

Police said the daughters, Sangeetha, 14, Saranya, 12, and Sabithra, 10, were found hanging in another room. “It looks like Lakshmi first aided the girls in committing suicide and then killed herself. No suicide note was left,” inspector (Manali) R Balamurugan said.

Police suspect they killed themselves because of frequent quarrels in the family. “We have registered a case of suspicious death,” an officer said. The bodies were sent for a postmortem.
