This was pretty interesting. I'd never heard of him before.

The remains resting in H.H. Holmes's coffin is being removed from its grave, and a team of researchers are hoping to find out if the they indeed belong to America's first serial killer. Last week, Philadelphia-based analysts started exhuming the body of what they presume to be Holmes, buried in Holy Cross Cemetery. He was supposedly executed by hanging just nine days before his 35th birthday, on May 7th, 1896, but rumors have persisted since his death that he actually escaped. Now, his descendants want to put a stop to this story once and for all.
