Overview
- Investigators opened the case after a 2024 tip and a police raid recovered child‑sexual material that led to his arrest and pretrial detention.
- In December 2024 a Cologne court originally sentenced him to three years and ten months for multiple sexual offences against minors.
- The Federal Court of Justice corrected that judgment by ruling some offences had been completed rather than attempted, which prompted a retrial.
- The Landgericht Köln increased his term to five years and three months on Wednesday after convicting him of sexually abusing a then‑16‑year‑old pupil, raping his 11‑month‑old daughter and having online chats to groom children.
- He is expected to lose his Beamten status as a teacher and remain jailed, and the case highlights how appellate review can change legal classification and increase penalties in child‑abuse prosecutions.
