12‑Year Sentence for Former Freehold Teacher Who Assaulted Student in Ocean County

12‑Year Sentence for Former Freehold Teacher Who Assaulted Student in Ocean County

FREEHOLD — A former Freehold Intermediate School science teacher has been sentenced to 12 years in state prison for repeatedly sexually assaulting a 15‑year‑old student she groomed over the course of months, according to Monmouth County court proceedings.

Allison Havemann‑Niedrach, 45, of Jackson, pleaded guilty earlier this year to first‑degree aggravated sexual assault. Superior Court Judge Jill Grace O’Malley delivered the sentence, calling the teacher’s conduct a “protracted campaign to seduce and abuse a little boy for her own satisfaction.”

Judge: “You are his trauma. You ruined him.”

During sentencing, Judge O’Malley said Havemann‑Niedrach exploited the teen’s vulnerabilities, isolated him at school, and used her own daughter as a cover story to maintain access to the victim. The abuse occurred in her car, at her Jackson home, and at a hotel in East Windsor between January and June 2024.

Investigators recovered more than 25,000 text messages, explicit photos, videos, and digital evidence linking Havemann‑Niedrach to the assaults.

She must serve 85% of her sentence—about 10 years and two months—before parole eligibility. She will also be required to register under Megan’s Law, remain under lifetime parole supervision, and is permanently barred from public employment.

Victim Speaks: “For two years, I thought it was my fault.”
The teen, identified in court only as Y.N., bravely addressed the judge, describing how the abuse followed him into high school, damaged his ability to trust others, and caused academic struggles. He said publicity surrounding the case made him feel exposed among classmates.

Despite the trauma, he offered forgiveness to Havemann‑Niedrach — a moment that brought her to tears after remaining emotionless throughout most of the hearing.

Judge O’Malley praised the teen’s courage, noting that many adult victims cannot face their abusers in court.

Grooming Began Inside the School

Court records show Havemann‑Niedrach first met the victim as his sixth‑grade substitute teacher, later becoming his eighth‑grade science teacher. She gained access to his personal information, brought him food and clothing, and isolated him during lunch periods.

Prosecutors said she created a false narrative that her daughter and the victim were dating, allowing her to maintain contact without raising suspicion.

Defense Sought 10 Years; Judge Said 15 Was Justified

Defense attorney Matthew Mordas requested a 10‑year sentence, citing Havemann‑Niedrach’s medical issues and lack of prior criminal history. Judge O’Malley rejected the request, saying the severity of the harm and abuse of trust warranted a sentence “north of 15 years,” but she honored the negotiated 12‑year plea agreement.

The plea deal resulted in the dismissal of additional charges, including manufacturing child sexual abuse material, official misconduct, and endangering the welfare of a child.

Aftermath

The victim’s mother told the court she hopes no other child or parent experiences what her family endured. Havemann‑Niedrach apologized briefly, saying she takes “absolute accountability” and hopes the family finds peace.

Judge O’Malley made clear where responsibility lies: You are his trauma.”
