I just recently listened to the audio version of this book, which featured an apparently famous murder in NY at the end of the nineteenth century, though the story was unfamiliar to me.

It features a man who was murdered and then cut up (along the more traditional anatomical planes) and apparently there was an attempt to boil his legs, though I never understood why.
His upper torso was found in one package, his lower torso in another, and then later his legs were found. His head was apparently never found.
In spite of all the bizarre details (which this case promises to match) it was a fascinating story.
