Senior Superintendent of Police Vaibhav Krishna said Prema Bist, 46, hanged herself from the ceiling fan of a room while her daughter, 28, was found dead with injury marks on her throat.
Superintendent of Police Shlok Kumar said the police found a suicide note written by the mother, addressed to her younger daughter Monika, who works in Gurugram: "Please excuse me for this harsh step. I love you too much. Take care of yourself and settle (down) after finding a good boy. I didn't want to leave you alone but I am forced by circumstances to do so. I will protect you from all miseries. I will be present whenever you remember me."
Balwant Singh and Monika left home at 9.30 a.m. on Tuesday. In the evening, at 5, when Balwant Singh telephoned his home and didn't get any reply, he alerted a friend who found the house gate locked. It was broken when Balwant Singh reached home.
