A teacher described as “obsessed” has confessed to sexually assaulting a 15-year-old boy, having reportedly exchanged around 25,000 text messages with him.
Allison Havemann-Niedrach, a 45-year-old mother of two from New Jersey, has admitted to a charge of aggravated sexual assault, potentially leading to a 12-year prison sentence.
According to a police inquiry, the inappropriate relationship between Havemann-Niedrach and the teenager began in January 2024 and continued until her arrest in June of the same year. Witnesses reported instances of the teacher having lunch with the student daily and engaging in physical contact perceived as flirtatious.
The boy’s sister witnessed him in the teacher’s car before he disclosed the illicit affair to his mother. Authorities discovered a trove of text messages, photos, and videos exchanged between the teacher and the student, totaling around 25,000.
Prosecutors revealed that the teacher, characterized on her LinkedIn profile as a dedicated and results-oriented educator, displayed an “obsessive” behavior towards the victim. The victim disclosed to police that their encounters took place at the teacher’s residence and hotels.
The sentencing is scheduled for May 7, 2026, with the prosecution pushing for 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, admitted to sexually abusing a teenage student. The criminal activities started in January 2024 and lasted for approximately six months until her arrest in June 2024. An indictment was issued in March 2025 following an investigation by the MCPO Special Victims Bureau and Freehold Borough Police Department.
The sentencing, tentatively set for May 7, 2026, could result in a 12-year prison sentence, loss of public office, surrender of teaching license, Parole Supervision for Life, and registration as a sex offender under Megan’s Law. The state intends to enforce the No Early Release Act, requiring 85 percent of the sentence to be served before parole eligibility.
