Back in the fall of 1888, five prostitutes were killed in east London and a man calling himself Jack the Ripper wrote several letters to the London police saying he was responsible.
He was never caught.I just started finding things, said Mark Potts of Berks County. And when you find that much, handwriting and what not, I'm very confident.Potts collected every letter he could written by Jack the Ripper, including those to the police.
It was almost like he was baiting them, said Potts.He also collected anything he could find written by another mass murderer in the United States, named Herman Mudgett or H. H. Holmes.
I never heard of a building being built just to kill people, said Potts, but he did that. I came up with stuff nobody noticed before.Potts said he took a letter in which Jack the Ripper wrote the word "Philadelphia" and then the confession that Holmes or Mudgett wrote that was published in the Philadelphia Inquirer and compared the two Philadelphias.
And it's not just the writing he said he found. The BBC did a special profile on Jack the Ripper and came up with an image.
Potts wrote his article for the Journal of the Whitechapel Society and he said Herman Mudgett is Jack the Ripper.
His lack of whereabouts in the U.S. at the time and all the handwriting, it's him, said Potts. It's gotta be him.
There's just no doubt about it.
