Greeshma was in a relationship with Sharon, but had gotten engaged to an Indian Army officer. She was then actively looking for a way to get out of the relationship with the Kerala youth and decided to lace his drink with poison on October 14.

Earlier, WhatsApp chats revealed that Greeshma's family had a superstition that the man who marries her first would die soon.
Sharon's family said that in order to prove that this is a superstition, he took Greeshma to Vettukadu Church, and tied a mangalsutra on her at home.
