The morning air in Eau Claire, Wisconsin, usually carried the crisp, clean scent of approaching autumn, but on September 15, 1995, the atmosphere felt heavy, charged with an unspoken dread. Monica Lucas Savage stood by the window, watching her thirteen-year-old daughter, Jessyca, climb into her father’s car for a routine weekend visit. There was no reason to suspect that within forty-eight hours, her world would shatter into a million jagged pieces.
The silence that followed two days later was broken by a phone call that every parent fears. It wasn’t Jessyca on the other end, but her ex-husband, Dale. His voice was thin, wavering with a hesitation that made Monica’s blood run cold.
“I think Jessyca might have run away,” he stammered.
“Run away? That’s nonsense!” Monica shouted, her heart hammering against her ribs like a trapped bird. “Who is she with, Dale? Tell me right now!”
The silence on the line stretched, agonizing and thick. When he finally spoke, the name he uttered felt like a physical blow to her stomach.
“Steven Oliver.”
The name tasted like poison. Steven Oliver—the neighbor, the “friendly” school teacher’s aide, the man who had systematically inserted himself into their lives under the guise of mentorship. Monica felt a chill race down her spine, a primal maternal instinct screaming that her daughter hadn’t run away. She had been stolen.
Days later, a letter arrived. The handwriting was Jessyca’s, but the soul was missing. “Don’t come look for me. I’m in a safe place,” it read. Monica stared at the ink, her vision blurring. She knew how her child spoke; she knew how she thought. These weren’t Jessyca’s words. They were a script—dictated by a monster.
While the police began their slow, bureaucratic crawl, Jessyca was already hundreds of miles away, trapped in a moving tomb. She had woken up in the back of a car, her ankles lashed to the floorboards, her wrists bound tight behind her back. The man she once trusted as a teacher leaned over her, his face a mask of cold malice.
“You piece of nothing,” he hissed, his voice devoid of the warmth he used in the classroom. “Nobody wants you. Nobody loves you. You’re never going home, and no one is looking for you.”
As the car sped toward an unknown destination, Jessyca realized with a sickening jolt that the man who had promised to help publish her stories was now writing a horror story of his own—and she was the unwilling protagonist.
The nightmare did not begin on that September morning; it had been simmering in the shadows for four years. In 1991, Steven Oliver and his son, Ryan, moved in next door to the Mullenberg family. To the outside world, Oliver was a dedicated father and a helpful neighbor. When he secured a job as a teacher’s aide at Jessyca’s elementary school, it seemed like a natural fit. He noticed Jessyca’s talent for writing and art, inviting her to join a specialized writing club.
However, the “club” was a calculated trap. Oliver began isolating Jessyca, pulling her away from her peers. Inside the school walls and the confines of his home, the grooming turned into a predatory campaign of terror.
“Nobody knew,” Jessyca would later recall. “Oliver would pull me aside, follow me into his house, and then he would lock me up in one of the rooms. He would set me on his lap. I always went home feeling dirty, feeling like I did something wrong.”
He used psychological warfare to dismantle her self-esteem, telling her she was ugly, stupid, and unlovable. When words weren’t enough, he turned to physical violence and sexual abuse. His ultimate weapon was a threat that kept her silent for years:
“If you tell anybody, I will kill your family members, and then I will kill you.”
To a young girl, his word was law. She bore the bruises and the shame in silence, her only priority being the safety of her mother and brothers. By the time 1995 arrived, Oliver was ready to escalate his obsession. He convinced Jessyca’s father, Dale, that he was taking her to Madison to meet a publisher. Trusting the “nice” teacher’s aide, Dale let her go.
In the aftermath of the disappearance, investigators descended upon Oliver’s home. What they found was a chilling inventory of intent. Hidden away were receipts for duct tape, heavy rope, and a knife—tools of restraint purchased long before the “trip” began.
“This wasn’t a spur-of-the-moment thing,” noted an investigator. “Steven Oliver did a lot of preparation for this abduction.”
As the FBI joined the hunt, Oliver was busy erasing Jessyca’s identity. At a nondescript location, he forced her to sit still as he hacked off her hair and dyed it a dark, muddy color. He gave her a new name: Cindy Johnson. He was now Dave Johnson.
“From now on, you call me Dad,” he commanded.
They moved like ghosts between cheap motels. To the hotel clerks, he spun a heartbreaking tale: they were a father and daughter starting over after a tragic car accident that killed Cindy’s mother and twin brother. The staff, moved by the “sob story,” never questioned why the young girl looked so terrified or why she was never seen outside the room.
Inside the motels, the conditions were squalid.
“The first time I went into the hotel room, it was really dark and scary,” Jessyca remembered. “Dusty, cockroaches everywhere. It was gross.”
Oliver’s paranoia grew. He scanned parking lots for Midwestern license plates, fearing the reach of the law. He eventually moved them to a hotel undergoing renovations, securing a room in a back wing closed to the public. There, the walls were thick, and the screams of a thirteen-year-old girl would go unheard.
He kept her tied to the bed for hours on end. He rationed her food as a method of control.
“I wasn’t allowed to eat whenever I wanted to because he said I was fat and ugly. I was beaten hard in the stomach by his fist until I could barely walk.”
Desperate, Jessyca waited for the rare moments he left the room. She found a rotary phone and tried to call home, her fingers trembling as she dialed the familiar number. But the line was dead—or worse.
“I found out he had rewired it. If you dialed a five, it could be a six. If you dialed a seven, it could be a four. There was no way I was making a phone call to anybody.”
The psychological breaking point neared. After months of hearing she was worthless and that her family had stopped looking, the image of her mother began to fade. Jessyca Mullenberg was dying, and “Cindy Johnson” was taking her place.
Back in Wisconsin, Monica refused to let the trail go cold. She worked tirelessly with her brother, Steve, to keep Jessyca’s face in the public eye. They placed her image on billboards, the backs of semi-trucks, and finally, on the national television show America’s Most Wanted.
“I wouldn’t have given up,” Monica said, her voice iron-clad. “I don’t care if it was ten years; I would still be looking for her. I always felt she was alive.”
On December 28, 1995—104 days after the abduction—the breakthrough arrived. A tip came into the America’s Most Wanted hotline from a woman in Houston, Texas, who recognized the “Johnsons” at a local motel.
In the dead of night, the silence of the motel hallway was shattered by a heavy thud against the door.
“Don’t you dare do anything!” Oliver hissed, clutching his knife.
“This is the FBI! Open up!”
The door gave way. Men with badges and guns swarmed the cramped, cockroach-infested room. Jessyca, huddled in the corner, didn’t feel relief—only confusion.
“I didn’t know I was being rescued,” she admitted. “I just saw strangers coming into the room. I was freaking out, wondering if this was real or if I was actually going home.”
When agents asked for her name, she whispered, “Cindy Johnson.” She was so deeply traumatized she no longer recognized her own identity. It wasn’t until they took her to the field office and put her on the phone with Monica that the walls Oliver had built began to crumble.
“Mom?”
The sound of her mother’s voice was the key that finally unlocked the real Jessyca.
“After she started talking to me, I started remembering that my name was Jessyca and that she was my mom. I was really excited. I knew I was going home.”
The reunion at the Houston airport was a moment of pure elation. Monica saw a girl with short, dark hair running toward her—a girl who looked different but whose soul was unmistakably her daughter’s. They collapsed into each other’s arms, weeping.
“It was a late Christmas miracle,” Monica said. “The best day of my life.”
But the return home was not the end of the struggle. The physical toll was immense; Jessyca required multiple surgeries to repair the damage from Oliver’s beatings. The social toll was perhaps even more cruel. At school, she was met not with universal sympathy, but with the cold edge of bullying.
“People would ask, ‘Why didn’t you run? Why didn’t you get away?’ They even said I was lucky for getting kidnapped because of the attention. I felt so much guilt.”
Despite the cruelty of her peers and the haunting memories of the “writing club,” Jessyca refused to be a victim. In June 1996, she faced her monster in court. Oliver’s lawyers tried to claim she had gone willingly, but Jessyca stood tall. She testified for hours, reliving every harrowing detail to ensure he could never hurt another child.
Steven Oliver was sentenced to 40 years in prison without the possibility of parole.
The girl who was told she was “damaged goods” proved the monster wrong. Jessyca graduated from college with honors, majoring in Psychology and minoring in Criminal Justice. She wanted to understand the darkness so she could help others find the light.
Though doctors feared the physical abuse might have left her unable to conceive, Jessyca defied the odds once more. She married and became a mother to children of her own—a living testament to a future Oliver tried to steal.
Today, she travels to schools to speak about abuse and survival.
“I survived so that I could continue living a life and being a part of the community,” she says. “I’m a symbol of hope to parents of missing kids. If I can help one person come forward, all the pain and all the nightmares I dealt with… it’s worth it.”
The story of Jessyca Mullenberg is no longer a story written by a predator in a dark motel room. It is a story of a mother’s iron will, a daughter’s resilience, and the light that refused to go out, even after 104 days in the dark.
