Leo Winkler was a man who also happened to be a serial killer named "The Dead Rose Slasher".

According to Donald Mallard, Winkler had been born to a drug-addicted woman named Rose and as such, Winkler later incorporated that into his killings, leaving a rose at the scenes of his victims with the team even believing that Winkler did this in order to prevent other people like himself, ie, sons born to drug-addicted mothers being created.

They determined that Winkler was the serial killer but they soon realized that Winkler was not the killer they were looking for as he had died a year prior to the recent killings beginning, further strengthening the theory that the team were actually searching for a copycat.
