This post explains what happened, how the courts handled the case, and which school policies changed as a result, so you can understand the facts and the system response.

Expect a clear timeline of the sleepover assault allegations, a breakdown of the legal proceedings and sentencing, and a look at the new rules schools adopted to prevent similar harm. For more background on the sentencing and the case’s local impact, see the coverage by Kenosha County Eye.

Overview of the Sleepover Assault Case

The case centers on multiple allegations that a school employee abused children during a sleepover and on school time, prompting criminal charges, an investigation by local law enforcement, and policy changes in area schools. Court filings and local reporting identify the accused, several victims, and the charges that followed.

Background on Anna Marie Crocker and Her Role

Anna Marie Crocker worked as a teacher’s aide at Riverview Elementary in Kenosha County. She interacted daily with students in her classroom and participated in after-school activities that put her in close contact with children.
Parents and colleagues described her as a familiar school employee before allegations emerged.

School and court records show Crocker faced separate allegations involving multiple boys. The criminal complaint lists charges tied to her role as a staff member who used that position to gain access and trust. That context intensified community concern because she held a position meant to protect students.

Details of the Sexual Assault Incidents

Investigators say the most serious incident occurred at a sleepover Crocker hosted where a child under 13 was awakened and sexually assaulted. Deputies allege the act included sexual intercourse and that other offenses followed, such as filming and possession of explicit images, prompting counts of sexual exploitation of a child and possession of child pornography.
One county filing identifies both first-degree child sexual assault and additional counts reflecting separate acts.

Victim statements and charging documents describe repeated contacts and at least two identified victims at preliminary hearings, with prosecutors indicating more alleged victims emerged as the probe continued. The reported acts and the accused’s method of access—hosting or otherwise engaging minors—formed the basis for the child enticement and child sexual assault allegations.

Investigation and Arrest Timeline

Kenosha County Sheriff’s Department opened a criminal investigation after a parent reported suspicious behavior. Detectives executed interviews, collected digital evidence from phones, and identified potential additional victims during forensic review.
Prosecutors filed a criminal complaint charging Crocker with first-degree child sexual assault, sexual exploitation, and related counts once investigators gathered corroborating statements and electronic evidence.

Crocker pleaded guilty in December and was later sentenced to more than 50 years in prison. Court dockets and local press coverage document preliminary hearings, new victim identifications, and the sheriff’s department statements about ongoing forensic review that produced additional charges during the investigation.

Legal Proceedings and Sentencing Details

The case moved from investigation to plea and then to a lengthy sentencing hearing that detailed charges, witness testimony, and the judge’s rationale. Court filings, prosecution statements, and victim impact testimony shaped the final prison term and the supervision that will follow.

Charges Brought Against Anna Marie Crocker

Prosecutors in Kenosha County charged Anna Marie Crocker with seven felony counts related to sexual assault and exploitation of children. The counts included first‑degree sexual assault of a child and related criminal sexual conduct charges that carry severe penalties under Wisconsin law.
The Kenosha County District Attorney’s office pursued the case after an investigation by the Kenosha County Sheriff’s Office that involved forensic interviews, digital evidence recovery, and search warrants. Evidence listed in court papers tied Crocker to multiple incidents, including assaults that occurred during a sleepover at a private residence.

Charges exposed Crocker to well over a century in theoretical maximum exposure under the statutes. Prosecutors filed felony complaints and later accepted pleas on several counts, narrowing the contested issues to facts and sentencing rather than a jury trial.

Key Figures in the Trial and Sentencing

Judge David Hughes presided over the Kenosha County Circuit Court sentencing hearing. He evaluated presentence reports, victim statements, and legal arguments before announcing a term that would reflect both statutory ranges and aggravating factors.
Deputy District Attorney Rosa Delgado acted as the lead prosecutor, presenting the state’s case, summarizing investigative findings, and arguing for a lengthy custodial sentence given the nature of the offenses. Defense counsel raised mitigating factors, though the court found them insufficient to significantly reduce exposure.

Media outlets including WISN covered courtroom developments and published reporting that tracked the charges and reactions from the community. The case also drew attention through true crime newsletters and local reporting that named other regional cases for context, such as Madison Bergmann and Xavier Solis, though those were separate matters that influenced broader discussion about school staff misconduct.

Courtroom Testimony and Victim Impact Statements

Courtroom testimony included law enforcement witnesses who described interviews, digital forensics, and evidence collection procedures. Forensic interviewers recounted child interviews and investigators detailed chain‑of‑custody for seized devices. Testimony aimed to establish timeline, locations, and the defendant’s access to victims.
Victim impact statements proved central to the sentencing phase. Family members and survivors read statements describing emotional and psychological harm, disruption to schooling, and ongoing therapy needs. Those statements influenced the court’s view of harm and the need for a sentence that accounted for long‑term consequences.

The prosecution highlighted consistency across victim statements and corroborating digital evidence. Defense arguments emphasized remorse and any steps toward rehabilitation, but the emotional weight of the impact statements remained a decisive factor for the judge.

Sentencing Outcome and Prison Term

Judge Hughes sentenced Crocker to 51.5 years in state prison followed by extended supervision under Wisconsin corrections statutes. The term reflects the court’s application of consecutive and concurrent sentencing principles across the seven felony counts.
The sentence ensures Crocker will serve a lengthy custodial term in a Wisconsin state prison, with the Department of Corrections retaining oversight during extended supervision after release. The Kenosha County Circuit Court docket and press releases from the Kenosha County District Attorney’s office documented the final entry.

Local coverage linked the sentence to policy responses in area schools and renewed calls for staff vetting and training. Reporting outlets, including a local Kenosha County Eye article, provided timelines and quoted court statements about the rationale for the imposed term.
