The duo went to Bengaluru and stayed at a lodge. The next day, Mohan told her to get ready to go for a pooja and asked her to leave all her gold ornaments. After, they reached a bus stand in Bengaluru, he convinced her to take a contraceptive tablet, but gave her cyanide instead. Believing it to be a contraceptive pill, she consumed it and died. It is the same Modus operand that Mohan used on all his victims.

A case was registered against Mohan, by the victim’s family in 2009.
