Mary Capps worked for Park City compliance — and didn’t get along with her boss. She describes him as many people would describe bad bosses: “mean, controlling, micromanaged everything.”
She said she felt like she was walking on eggshells around him because she never knew when he was “going to snap.”
The difference between Capps’s boss and yours? Yours — hopefully — isn't a serial killer.
Capps’s boss, on the other hand, was Dennis Rader — otherwise known as BTK, or “Bind, Torture, Kill,” the notorious serial killer who terrorized Wichita, Kansas, between 1974 and 1991.
In Oxygen’s "Snapped: Notorious BTK Killer," Mary Capps recalls an incident that gave her a “glimpse of looking in the eyes of BTK.”
Capps says she was searching for a file for him, and he just “kept screaming.” While she had her back to him, she heard the door shut. She swung around, only to be frightened by the look on his face.
She says she got behind the desk and screamed, “Dennis, open the door,” before using the intercom to say: “Someone get back here and help me.”
At that point, Capp recalls, Rader just turned and opened the door “as if nothing had happened.”
She says that though she complained about him every day, nobody listened to her because they thought he was a “good guy” — a church leader, a family man.
Capps told KAKE that Rader asked her if she had seen the drawing of BTK.
“You know it looks like me, I could be BTK,” Capps recalls Rader saying to her.
There is no evidence that shows Rader killed anyone during his time working as a compliance officer.
Rader, who fell quiet for more than a decade, reemerged in 2004 after the Wichita Eagle ran a story on the 30th anniversary of the unsolved murders of the Otero family. BTK then taunted the police with tantalizing bits of evidence — only to be felled by a traceable floppy disk.
Capps has filed complaints about her time working for Rader and has even published “My Boss Was BTK… I Was The Next Victim,” a book where she argues that she has PTSD from working for him, and, on her book cover, that she had nightmares that started “months before his arrest, her subconscious trying to warn her of danger.”
While it is unclear if Rader ever did intend to focus his energies on Capps, it’s known that Rader had targeted people who worked for the same company as him before.
Rader, who worked on an assembly line at Coleman in the early ‘70s, stalked Julie Otero, who also worked at the factory, culminating in the brutal murder of the Otero family that terrified Wichita for years to come.
His next “project,” or “PJs,” as he called them was 21-year-old Kathryn Bright who also happened to work at the Coleman plant, according to Fox News.
At a later job installing alarm systems for ADT security services, Rader appeared to find himself quite unpopular.
"None of us liked him. We just kind of tolerated him. He did his job, we did our job," said an ADT co-worker to the Wichita Eagle.
Rader, 73, is currently serving 10 consecutive life sentences at El Dorado Correctional Facility in Kansas.
From nightmare boss to just plain nightmare, BTK’s fascinating double life will be uncovered in "Snapped: Notorious BTK Killer” on Oxygen.
