on a screen. Shyam knew how Sumesh had done it but was keen that Sumesh has to say everything. In a flashback, Sumesh and Rashmi studied in same college. Even though both had fallen in love with each other Rashmi soon began opposing Sumesh as per her family's wish. Sumesh understands her and tells her to follow her parents's wish. But shortly he visits her and overhears her conversation with her parents. He came to know it was Rashmi who wanted to marry Mohan and her parents was against it as they were afraid of the insurities in marrying a politician and she was cheating Sumesh all this while. So in order to seek revenge, Sumesh decided to kill Rashmi after coming to know that she is married to Mohan. He seeks the help of his friend and got addicted badly in drugs. He learnt the schedule of Rashmi in the absence of Mohan and had stolen the key of Rashmi's bedroom to make a duplicate one. One night after arriving from Bangalore, Sumesh gets down from bus and rushed towards Rashmi's house without his friend's knowledge. This was the time Mohan went from home after an argument with Rashmi regarding freedom. So he waited for his chance and bought required tools along a bottle of strong poison with him. At first he poisoned a jar of milk kept in the room. But the plan was a failure. Nextly he had climbed up the ladder to reach the ventilator and attached some pieces of plastic pipes after tying a thread on its end. As Rashmi slept, Sumesh bought the thread to Rashmi's mouth without even a single noise. He then sent poison to Rashmi's mouth via the pipe and thread. That was how Rashmi lost her control and died. After that he burnt all the materials including bottles, gloves and dropped the bottle that contained poison to make everyone believe that it was a suicide. Back to the present, Shyam further explains that he understood the method of murder by observing the poison drops being dropped from Rashmi's bed to the ventilator in a straight way and often the drops were of different size. He further explained that the culprit had gone inside the house to switch off the inverter. This was to make the ceiling fan out of use in order to keep the thread used for the murder
