This is the infamous “Lusk Letter” sent with half of a preserved human kidney to the chairman of the Whitechapel Vigilance Committee, George Lusk, in October 1888, during the Ripper killing spree. The author claimed to have ‘fried up’ and eaten the other half of the kidney and insinuated himself to be Jack the Ripper.
This confession letter, among thousands sent to Scotland Yard and Reporters, is from the serial killer we know today as Jack the Ripper.
The letter reads:
I send you half the Kidne I took from one women prasarved it for you tother piece I fried and ate it was very nise. I may send you the bloody knif[e] that took it out if you only wate a whil[e] longer
“Catch me when you can Mishter Lusk”
There was at least one, maybe two, copy cat killers around the same time. Some of the murders attributed to Jack the Ripper were not his. And a few other murders outside of his suspected time of operations, were in fact, his.
