This revelation exposes the corruption that contaminated the original investigation.

Venkatesh was Chidambaram's former colleague who led the fight against the original Smile Man murders. He disappeared on a mission five years before the present timeline.

Chidambaram retaliated in self-defense and shot Venkatesh, noticing the Smile Man mark on Venkatesh's face before driving away.

Chidambaram was targeted because he wrote a book about the Smile Man case, bringing renewed public attention to the murders.

Prabhu is a mortuary worker who is revealed as the actual Smile Man killer. His psychology stems from childhood habits of harming friends to force smiles on their faces after death.
