Overview
- The sentence was imposed on Aug. 28, 2026, when Allison Havemann‑Niedrach received 12 years in state prison and must serve at least 85% of the term, keeping her incarcerated until at least 2036.
- Havemann‑Niedrach pleaded guilty in January to a single count of aggravated sexual assault as part of a plea deal that dismissed six other counts from a seven‑count indictment.
- Prosecutors say the abuse occurred from January through June 2024 and included sexual encounters at the teacher’s home and hotels plus roughly 25,000 sexually explicit messages, photos and videos exchanged with the 15‑year‑old.
- School staff concerns about inappropriate contact in 2023 prompted the probe, and she was arrested at her parents’ home on June 27, 2024; bodycam footage shows she told officers her phone had been "destroyed."
- The victim delivered an impact statement describing long‑term trauma and suicidal thoughts, the judge condemned the breach of trust—ordering no contact—and the case resulted in permanent revocation of her teaching credentials and required registration under Megan’s Law.
