Smiley Face Graffiti May Be the Clue to Solving Hundreds of Murders

Hundreds of deaths thought to be accidental drownings may actually be gruesome murders, committed all over the country by an organized group of serial killers.

The horrifying story sounds like something out of a Hollywood movie script. But a group of detectives exploring the cases are convinced of their theory.

Veteran NYPD detective Kevin Gannon says their deaths may be the work of multiple killers. He says all of them are linked by one chilling clue: graffiti of a smiley face nearby. “This is a well-structured, organized group,” Gannon says.

The theory is laid out in the new Oxygen docu-series “Smiley Face Killers: The Hunt for Justice.”
