Overview
- The Oberlandesgericht Koblenz convicted the 39-year-old of secret-agent activity and imposed a prison term of two years and eight months.
- Prosecutors said he contacted Chinese state entities in summer 2024 to offer sensitive U.S. military information and was arrested on 7 November 2025 before any transfer occurred.
- The court identified him as Martin D., a U.S. citizen who worked from 2017 to 2023 for a Defense Department contractor on U.S. bases in Wiesbaden and Mainz.
- Parts of the proceedings were closed to the public because open hearings could endanger Germany’s security interests, according to the court.
- The defense and defendant waived appeals, and the federal prosecutor indicated it may consider further legal steps.
