A new twist on the death of one of America's first and most notorious serial killers could change everything we know about "The Devil in the White City."
H.H. Holmes was portrayed in the widely popular Chicago-based novel as a con man, swindler and infamous murderer during the 1893 World's Columbian Exposition. He confessed to as many as 30 murders but may have been responsible for up to 200.
At 67th and Wallace, Holmes built a three-story World’s Fair Hotel that would later become known as his "murder castle."
The hotel was filled with stairways that led to nowhere, doors that opened into brick walls and others outfitted with locks that would seal a person inside.
Holmes was believed to have been hanged for his crimes on May 7, 1896, but mysterious details have lingered, questioning what many thought they knew about his death.
Was justice actually served? Decades later, many still wonder what really happened to Holmes.
NBC 5 investigative reporter Phil Rogers reveals a new twist that could change that forever, tonight at 10 p.m. on NBC 5 News.
