In addition to an investigation of the real-life Conjuring house that’ll air on Halloween night, Zak Bagans and the “Ghost Adventures” team are also bringing a brand new miniseries to the Travel Channel this October: “Ghost Adventures: Serial Killer Spirits.” The four-part miniseries will focus on America’s most notorious serial killers.

Exploring haunted locations associated with infamous serial killers, the team tackles the question: does evil linger? The miniseries kicks off with America’s first serial killer H.H. Holmes, who gained a new level of infamy in the international bestseller “Devil in the White City,” which has been optioned into a series by Leonardo DiCaprio and Martin Scorsese.

As the curiosity surrounding Holmes and the thirst for information on him continues, Zak Bagans and the ghost Adventures team returns to the only remaining murder house with one of Holmes’ living relatives to take a look at the evil presence he left behind.
