H.H. Holmes

A 2004 documentary by John Borowski covering the crimes of H.H. Holmes, the fraudster and serial killer who built a 'Murder Castle' near the 1893 Chicago World's Fair.

The H.H. Holmes murders are a series of killings attributed to con artist Herman Mudgett in 1890s Chicago, with only some victims confirmed and many claims disputed by historians.

From H.H. Holmes' murder castle to the St. Valentine's Day Massacre, Chicago's mob bus tour puts America's darkest history on full display.

Chicago Crime Tours runs a bus tour through the Windy City covering H.H. Holmes, Al Capone, John Dillinger and the city's darkest chapters.

In 1892, H.H. Holmes constructed a three-story building in Chicago's Englewood neighborhood that would become synonymous with some of America's first confirmed serial murders. What locals called the 'Murder Castle' was actually a hotel marketed to World's Fair visitors—a place where at least six confirmed victims vanished.
