After 125 years, "Jack the Ripper" has apparently been debunked.

Former murder investigator Trevor Marriott spent 11 years poring over Scotland Yard files and said he learned that the legend of Jack the Ripper as we know it is wrong, Britain's Daily Express reports.

He also said he's figured out who the real Whitechapel killer might be.

Marriott concluded that Central News Agency journalist Thomas Bulling reportedly coined “Jack the Ripper” and sent police a letter from “him” 1888.

In Victorian-era London, five prostitutes' murders were supposedly committed by Jack the Ripper, a rich, educated man -- possibly a doctor -- who legend has it removed organs from the bodies of his victims.

The story has been told in many books and movies over the years, including 2001’s From Hell, which starred Johnny Depp.

Marriott, who has written several books on the subject and is currently on a U.K. speaking tour, said these works are to partially to blame for popularizing an inaccurate conception of who “Jack” was.

“You have to ask yourself if ‘Jack’ is an urban myth. Around 80% of the books about him have a picture of a chap on the front stalking the streets of London in a long black cape and a top hat,” Marriott told the Express.

“They were the clothes of an upper class, wealthy man. But back in 1888 if someone dressed like that had actually walked around Whitechapel in the dead of night they wouldn’t have lasted five minutes."

So who is the real killer?

Marriott said some of the murders were likely committed by Carl Feigenbaum, a German merchant seaman who was docked at Whitechapel during the killings and executed at age 54 for a Ripper-style murder in New York in 1896.
