Jack the Ripper is the most notorious of all serial killers. There have been more books written and more movies made about him than any other murderer in history. The case of the infamous criminal has fascinated people for more than a century, and most intriguing of all is the fact that no person was ever charged with the crimes. Suspects have run the gamut, from barbers, lawyers, and famous authors, to even doctors. However, Jack the Ripper may have finally been identified, according to a UK businessman who privately funded an investigation into the 19th century case, and it turns out the killer wasnt a doctor, but a 23-year-old Polish immigrant named Aaron Kosminski.
