Dehradun: A widow, who survived a suicide attempt last month but lost her two mentally-challenged children, allegedly ended her life by consuming poison in Harrawala village here.

Police said Vidya Devi (42) was found dead in her house by neighbours last evening. As the house was bolted from inside villagers broke open the door, only to find her dead.

On December 20, Devi, a mother of three, had attempted suicide after killing her mentally-challenged children - Shivam (18) and Rachna (17) by giving them poisoned food.

While the children died in the hospital, Devi survived. After treatment, she was living with her brother and had returned home only yesterday.

Devi had sent her another daughter - Rajni (19) to her sister's house on December 19.

Her husband Vijay died of heart attack in November last and the widow was left with no source to feed the four-member family, including two mentally-challenged children, police said quoting villagers.
