Who Is Abigail Faust? Former Hudson Teacher Arrest

Abigail Michelle Faust is a former fifth-grade teacher at River Crest Elementary School in Hudson, Wisconsin, who pleaded guilty in September 2026 to child sex crimes after investigations uncovered allegations involving both an elementary-school student and a teenage boy whose family had employed her as a nanny.

Faust, 25, became part of a broader investigation that also involved former River Crest teacher Madison Bergmann. Investigators said the two teachers exchanged messages discussing inappropriate interactions with boys. Faust later faced criminal cases in Wisconsin and Minnesota before entering guilty pleas in Wisconsin in September 2026.

What Did Abigail Faust Admit To?

The case included allegations that Faust repeatedly sexually assaulted a teenage boy whose family had employed her as a nanny. The boy told investigators that Faust had worked for his family since 2021 and that their interactions eventually became sexual. Court documents described provocative messages and photographs as well as repeated sexual contact. [KSTP]

The Minnesota Star Tribune reported that the alleged sexual contact began in December 2023, when the boy was 14, and continued for months. Faust was eventually charged in Washington County, Minnesota, with third-degree criminal sexual conduct. [Minnesota Star Tribune]

Faust Addressed Her Conduct In Court

During the September 2026 plea hearing, Faust acknowledged responsibility for her conduct rather than characterizing it as an isolated mistake. News reports from the hearing said Faust told the court that what she had done was not simply a mistake or lapse in judgment and said she had been receiving therapy. [KSTP]

The Teen Said Faust Sent Provocative Messages And Photos

The teenager told investigators that Faust began sending him sexually provocative Snapchat messages and photographs before the physical relationship began. He later described multiple incidents of sexual assault to law enforcement. [KSTP]

According to the criminal allegations, Faust sometimes acknowledged to the teenager that what she was doing was inappropriate and that she felt uncomfortable about her own conduct, but the sexual contact nevertheless continued. [KSTP]

Faust Was Also Accused Of Sexual Contact With Another Teen

Court documents also alleged that Faust had sexual contact with one of the teenage boy’s friends. Investigators alleged that the incident occurred while Faust was accompanying the family on a vacation. The allegations involving the nanny job ultimately resulted in criminal charges on both sides of the Wisconsin-Minnesota border because some of the alleged conduct occurred in Wisconsin and some in Minnesota.

Abigail Faust Was Originally Investigated Over A Fifth-Grade Student

Faust’s legal problems initially became public through an investigation into her conduct with a student at River Crest Elementary School. A student aide told investigators that Faust appeared unusually close to a boy in her class, and authorities later alleged that Faust kissed the child. [KSTP]

The boy later told a therapist that Faust had kissed him and forced him to hug her, according to the criminal complaint. Investigators also reviewed information suggesting Faust had told the boy not to disclose their interactions. [KSTP]

What Charges Did Abigail Faust Initially Face?

The original Wisconsin case included charges of failure to protect a child, causing mental harm to a child, child enticement and sexual misconduct by school staff. Those charges arose from allegations involving a River Crest student and from prosecutors’ claim that Faust knew about misconduct involving fellow teacher Madison Bergmann but failed to report it. [KSTP]

The investigation later expanded substantially after the family that had employed Faust as a nanny learned about the Wisconsin school allegations and contacted authorities concerning their teenage son. [KSTP]

How Is Abigail Faust Connected To Madison Bergmann?

Faust and Madison Bergmann were both fifth-grade teachers at River Crest Elementary School, and investigators discovered messages in which the two women discussed their interactions with boys. The investigation into Bergmann helped lead authorities to allegations involving Faust. [KSTP]

Prosecutors alleged that Faust knew Bergmann was engaged in an inappropriate relationship with one of her students but did not report it. Investigators were subsequently told that Faust herself had an unusually close relationship with another child. [KSTP]

Who Is Madison Bergmann?

Madison Lynn Bergmann is another former fifth-grade teacher from River Crest Elementary School who was convicted in a separate child sex-crime case. Bergmann pleaded guilty to child enticement and two counts of sexual misconduct by school staff in 2025. [KSTP]

Bergmann was sentenced to six years in prison followed by six years of extended supervision. Her case involved an 11-year-old student with whom investigators said she exchanged thousands of messages and had sexual contact. [KSTP]

Faust Resigned From River Crest Elementary School

Faust resigned from her teaching position at River Crest Elementary School in May 2024. The Hudson School District later said it had cooperated with law enforcement and had strengthened its training and policies concerning professional boundaries between staff and students. [KSTP]

Abigail Faust Also Faced A Minnesota Criminal Case

Faust was separately charged in Washington County, Minnesota, with third-degree criminal sexual conduct involving the teenage boy whose family had hired her as a nanny. The Washington County case was assigned court file number 82-CR-25-3678. [Washington County]

The teenager and his parents contacted Washington County authorities after learning about the allegations against Faust in Wisconsin. He told deputies that Faust initiated a sexual relationship with him and described repeated sexual encounters. [KSTP]

A Federal Lawsuit Also Named Abigail Faust

Faust was also named as a defendant in a federal civil lawsuit brought by the parent of a minor child connected to the River Crest investigation. The lawsuit alleges that Faust failed to intervene while Bergmann was grooming and sexually abusing a student and also names the Hudson School District as a defendant. [Federal Court Records]

The civil allegations are separate from Faust’s criminal guilty pleas and require their own findings in federal court.

When Will Abigail Faust Be Sentenced?

Faust’s sentencing is scheduled for December 15, 2026. Reporting on the plea agreement says prosecutors agreed not to request a sentence longer than 15 years. The sentencing judge will determine the final punishment within the applicable law and terms of the plea agreement. [KSTP]

Who Is Abigail Faust?

Abigail Michelle Faust is a 25-year-old former fifth-grade teacher from Hudson, Wisconsin. She taught at River Crest Elementary School before resigning in May 2024 and later became one of two former teachers from the school prosecuted in high-profile child sex-crime cases.

Faust’s September 2026 guilty pleas moved the Wisconsin criminal proceedings from the prosecution stage toward sentencing. Her case drew particular attention because of the multiple alleged victims, her former position as an elementary-school teacher, her work as a nanny and her connection to the separate Madison Bergmann prosecution.
