The Disappearance of Bianca Piper

Bianca was 13 years old. Her family called her "B." She had brown hair and brown eyes and stood five feet six inches tall. Her ears were pierced. She had scars on her arms and her legs and her abdomen. She loved horses, and she loved Barbie dolls, and she loved the color purple. Her teachers said she was artistically talented. She was an eighth-grader at Winfield Middle School in Winfield, Missouri, where she struggled in classes that the rest of her grade did not struggle in, because the bipolar disorder she had been diagnosed with as a small child had made school a different experience for her than it was for everyone else.

She took medication every day to keep her mood swings and her hallucinations at bay. When she was on her medication, the people who loved her said you could not even tell anything was wrong. When she was off her medication, she became disoriented, and she heard things, and she became frightened of things that were not there. She was 13. She was learning how to live with what her brain was doing to her. She was being asked to do this in a small rural town in Lincoln County, Missouri, in a household whose details have never been entirely clear to outsiders, with a mother whose decision to drop her on a gravel road in below-freezing weather has been the subject of every conversation about her case for more than two decades.

There is no way to write about Bianca that does not sit, eventually, in the hour between 6:15 p.m. and 8:20 p.m. on March 10, 2005. Two hours. The first hour was the hour Bianca was supposed to walk back to her house. The second hour was the hour her mother apparently waited before calling the Sheriff. There is no version of those two hours that is not the only thing about this case anyone has ever wanted to talk about. The body of a 13-year-old girl with hallucinations, no medication, freezing temperatures, and rural woods on either side of a gravel road has not, in twenty-one years, been recovered. People who walk that road every season have looked. Search teams have walked it. The dogs got nothing past her mother's car. The 270-mile-radius search produced not one piece of clothing. Bianca did not get lost in the cold. The cold did not take her.

Whatever happened to her happened in those first minutes. Either someone drove down McIntosh Hill Road that evening and took her, or something happened closer to home. Lincoln County investigators have ruled in the second direction and ruled out of it for two decades, and the file remains open in both directions. Phone records cleared the alibis the family gave. The Devlin task force found nothing. Hundreds of tips have come in over twenty years. None has produced Bianca.

In September 2025, the Lincoln County Sheriff's Office announced a comprehensive new investigation. They sent the original 2005 evidence back to forensic labs that had nothing like 2025 technology in 2005. They did four new searches of the property where the family used to live. They planned a fifth. Chief Deputy Wade O'Heron told reporters they were committed, in his words, one hundred percent to solving this case. Bianca's family is still waiting. So is Bianca, if she is still alive.

Bianca's father David Piper died in 2009 without knowing what happened to his youngest daughter. Her older sisters have lived through twenty-one years of being asked, at every family gathering, whether there is news. Her mother Shannon Tanner has lived through twenty-one years of being looked at by her own community in a particular way that does not soften with time. Whatever the truth is, every member of Bianca's family has paid a different price for the not-knowing.

Bianca deserved to grow up. She deserved to be a teenager who got to be a teenager, with all the difficulty that her brain and her family and her town would still have brought to that. She deserved her medication, every day. She deserved to live to 34, to be the woman the age-progression artists at NCMEC have tried to imagine her as. She got none of it. She got two hours on a gravel road in March of 2005. We are remembering her here because she was a kid who loved horses and Barbie dolls and the color purple, and because the small town of Foley, Missouri has not forgotten her, and because her sisters and her mother are still waiting for the phone call, and because somewhere there is a person who knows what happened to Bianca Noel Piper, and that person is the only person who can answer what twenty-one years of investigators and family and a small county sheriff's department have not been able to answer for them.
