Mamta Verma used a saree to hang herself from the iron angle of a ventilation window at her Matunda Road home yesterday, SHO at Bundi Sadar police station Anil Joshi said.
The reason behind the suicide is yet to be ascertained as no suicide note was recovered from the room, Mr Joshi added.
Prima facie, the woman is most likely to have taken the extreme step due to an argument with her son who is a sitting BJP councilor from Bundi, police said.
According to a family friend, the mother and son had a squabble last night over a family issue following which Ms Verma ended her life.
Believed to be a bold and aggressive lady, Ms Verma stayed with her two sons, while her husband works in Bhilwara district.
An investigation has been launched into her death, police added.
