A Wisconsin school administrator has been arrested and formally charged with multiple child sexual assault offenses after an anonymous tip prompted an investigation into her alleged relationship with a teenage student.
Kaitlyn Hintz, 32, the associate principal at Bonduel Middle/High School in northeastern Wisconsin, was taken into custody Monday, October 19, after detectives investigated allegations of inappropriate contact between the educator and a student.
The case has raised serious concerns among parents and school officials, particularly after investigators determined that the alleged conduct occurred outside school property.
According to the Shawano County Sheriff’s Office, authorities received an anonymous report October 16 through Speak Up, Speak Out Wisconsin, a statewide program that allows students and community members to report threats, abuse and other safety concerns.
Detectives immediately launched an investigation, conducting interviews and reviewing evidence before determining there was sufficient probable cause to arrest Hintz.
She was taken into custody three days later and booked into the Shawano County Jail.
On Wednesday, October 21, prosecutors formally charged Hintz with repeated sexual assault of the same child, second-degree sexual assault of a child and child enticement involving sexual contact.
According to a criminal complaint reported by local television station WLUK, the allegations involve a female student who was 15 years old when the reported encounters began in October 2024.
Investigators allege that the contact continued over an extended period and occurred at locations away from school, including an outdoor area near the student’s home and a park-and-ride lot.
The student’s identity has not been released, and authorities have declined to share additional personal information because of her age and the sensitive nature of the investigation.
Following the allegations, the School District of Bonduel placed Hintz on administrative leave and notified families about the investigation.
In a letter to parents and staff, Superintendent Joe Dawidziak acknowledged the seriousness of the situation and assured families that the district was cooperating with law enforcement.
“We recognize that this news is deeply concerning for our students, families, staff, and community,” Dawidziak wrote.
He emphasized that student safety remained the district’s highest priority.
School officials also clarified that investigators had not identified any communications involving the student that occurred through district-operated digital platforms.
Similarly, authorities said the alleged encounters did not take place on school district property.
However, the location of the alleged conduct does not change the seriousness of the criminal accusations or the responsibility schools have to protect students from inappropriate relationships with adults in positions of authority.
Wisconsin law establishes strict protections for minors, and criminal charges involving sexual contact with children can carry substantial prison sentences.
The most serious charge filed against Hintz, repeated sexual assault of the same child, is a Class C felony under Wisconsin law. A conviction can carry a sentence of up to 40 years in prison, depending on the circumstances and applicable sentencing provisions.
The other charges also carry potentially significant penalties.
Hintz was scheduled to make her initial appearance in Shawano County court Wednesday afternoon, October 21.
Authorities have not publicly confirmed how long she had worked for the School District of Bonduel or whether investigators are examining additional allegations.
The district serves middle and high school students in the small community of Bonduel, located approximately 25 miles northwest of Green Bay.
As the investigation continues, school officials are encouraging students, families and employees to immediately report any concerns about inappropriate conduct or student safety.
The Speak Up, Speak Out Wisconsin program allows individuals to submit confidential reports that can be reviewed by trained professionals and forwarded to law enforcement or school officials when appropriate.
The Shawano County Sheriff’s Office said the investigation remains active and that additional information may be released as the case progresses through the courts.
