The Pinkerton Detective Agency was initially hired to track H.H. Holmes. They found evidence linking Holmes to numerous frauds and scams.

Holmes' Castle in Chicago, before it was torn down. The building was sound-proofed, with many hidden passages and false walls. There was also a large furnace in the basement, which was used to burn Holmes' victims.

Minnie Williams was another victim of Holmes.

Judge Arnold presided over the case, and allowed Holmes to represent himself, though very shortly into the trial, Holmes asked for his former counsel to re-take the case.
