In Texas, convicted murderer Ed Bell claimed he killed 11 girls between Houston and Galveston back in the 1970s. Reporter Lise Olsen and detective Fred Paige investigated those claims and uncovered eerie ties between Bell and several unresolved murders. In particular, they focused on three cases: all of them, double homicides of teenage best friends.

Did Ed Bell really kill Debbie Ackerman and Maria Johnson, Sharon Shaw and Renee Johnson, and Brooks Bracewell and Georgia Geer? Why did investigators dismiss his confessions so quickly? And what about Ed’s claim of a massive brainwashing conspiracy called “The Program”?

Edward Harold Bell was serving a 70-year prison sentence for murdering a man when he sent a letter to Houston reporter Lise Olsen. He told her he’d also killed 11 girls in and around the Interstate-45 corridor between Houston and Galveston back in the 1970s. He named some of these victims and described others with initials, locations, and years. And he included a poem that he titled “The Eleven Who Went To Heaven.”

Lise joined the efforts of Detective Fred Paige to investigate Bell’s links to the unresolved cases he alluded to… and together, they uncovered a long list of eerie coincidences and compelling circumstantial evidence.

In the fall of 1994, a 13-year-old boy found a human skull in his backyard. Detectives later discovered thousands more bones scattered about his family's estate, a property known as Fox Hollow Farm. The remains belonged to the presumed victims of Herb Baumeister, an alleged serial killer active thought to be active in Indiana for more than a decade. The investigation closed in the late-‘90s without an arrest. 11 unique DNA samples were catalogued and 8 victims identified at the time, but officials suspect the remains belong to as many as 25 people.
