He looked charming with his whiskey brown hair with a golden tinge, evil smirk, and adoring demeanor due to which he was termed as Casanova’s killer by the media and the people.

Two of his victims who escaped his cruelty described him to the police as the most enchanting and hottest looking man they have ever met.
