S1·E162 Rajnaitik Hatyare Part 1

Archana ends her life by suicide. Her brother Kunal, though, is certain that her in-laws killed her in order to get the dowry. However, Archana's family and the physicians' assistance demonstrate that she was mentally disturbed. Later on, as the Tyagi family is celebrating their win, Kunal enters and points a gun at them, threatening to murder them. Suddenly, there is a blast, and everyone in the Tyagi family is dead, with the exception of Guruji and Nirmal Tyagi, Archana's spouse.
