A teacher described as “obsessed” has confessed to sexually assaulting a 15-year-old boy after reportedly sending him approximately 25,000 text messages. Allison Havemann-Niedrach, a 45-year-old mother of two from New Jersey, has entered a plea of guilty to a single count of aggravated sexual assault, potentially resulting in a maximum sentence of 12 years in prison.
According to a police inquiry, the teacher’s involvement with the teenager started in January 2024 and persisted until her arrest in June of the same year. Colleagues reported observing Havemann-Niedrach having lunch with the student daily, with one witness claiming to have seen her displaying flirtatious behavior by rubbing the boy’s back and neck.
The student’s sister witnessed him sitting in the teacher’s car before he disclosed the illicit relationship to his mother. Authorities discovered a trove of around 25,000 text messages, including photos and videos of the pair together, on the student’s phone.
Prosecutors revealed that the former educator, described on LinkedIn as a “passionate, results-driven, and sincere educator,” exhibited an “obsession” with the alleged victim. The victim informed authorities that their sexual encounters occurred at the teacher’s residence and in hotels.
A sentencing date has been set for May 7, 2026, with the prosecution seeking a 12-year prison term and the revocation of her teaching credentials.
The Monmouth County Prosecutor’s Office announced that Allison Havemann-Niedrach, a former teacher at Freehold Intermediate School, has acknowledged committing sexual offenses against a teenage student. The investigation revealed that the criminal acts began in January 2024 and continued for approximately six months until her arrest in June 2024, leading to an indictment in March 2025.
The sentencing is tentatively scheduled for May 7, 2026, where the State plans to request a 12-year prison term, forfeiture of public office, surrender of the defendant’s teaching license, Parole Supervision for Life, and registration as a sex offender under Megan’s Law, with 85 percent of the sentence required to be served before eligibility for parole under New Jersey’s No Early Release Act (NERA).
