Rare, original artifacts that offer direct, tangible links to some of America's most notorious cases — curated with strict ethical standards by profiler Phil Chalmers.
Each item — a handwritten letter, a personal belonging, an investigative document, a reconstructed crime-scene piece — is a primary source. Not a souvenir, but a forensic witness.
As you move through five themed rooms, consider how each piece helps answer the questions that matter: motive, method, and the systems that respond to violent crime. These are the largest private collections of their kind on public display anywhere in the world.
Examine artifacts and relics recovered from Ed Gein's Plainfield property — where his farmhouse, barn and shed once stood. His kitchen utensils, jewelry, personal items, sewing machine, and family tools.
The home was eventually burned to the ground and bulldozed, but these artifacts were recovered from the rubble and brought back to life — the largest collection of Ed Gein artifacts ever displayed in the world.

Artifacts and historical pieces owned and personally used by Dennis Rader, also known as BTK. Profiler Phil Chalmers has spent hundreds of hours on the phone with BTK, visited every one of his Kansas crime scenes, and studied his case in depth.
We hope this exhibit helps you understand the mind of a dangerous killer who hid in plain sight — the largest collection of Dennis Rader artifacts in the world.

Inspired by the infamous TV killer, the Dexter Room gathers the collectors, cannibals and body-hunters — Dean Corll, the Tool Box Killers, the Hillside Stranglers, David Parker Ray and more — around a chillingly familiar kill-table centerpiece.
It's one of five themed rooms, each built to trace how motive, method and opportunity collide.

A handwritten “Helter Skelter” manuscript and case pieces tied to Charles Manson and the killings that ended the 1960s — the crimes that gave the phrase its terrible second meaning.
Phil interviewed Manson himself, and this exhibit sits among the 130+ cases mapped across the Mindhunter Room.

The real, authenticated glasses Jeffrey Dahmer wore in his 1991 booking photo — verified by provenance experts and preserved under museum conditions.
One of dozens of one-of-a-kind pieces Phil received directly from the killers and their cases — including Dahmer's apartment silverware, a clown mask from John Wayne Gacy's home, and BTK's prison chess set.
More than 130 cases and killers are featured across the museum. Here's who — and where — you'll find them.
Self-guided, ~2 hours. Open daily 10 AM – 5 PM.
