Story summary

Manhattan judge approved Luigi Mangione’s emotional disturbance defense and ordered hearing records released.
Mangione is charged with murdering CEO Brian Thompson in December 2024 and faces trial on September 8, 2026.
Prosecutors will present video, a 3D-printed handgun, and a notebook showing hostility toward the insurance industry.
Defense attorney Karen Friedman Agnifilo warned that revealing the psychiatric strategy could prejudice Mangione’s stalking case October 13, 2026, where it is unavailable.

History

Historical Context

In May 2013 Defense Distributed posted the Liberator’s CAD files, which were downloaded over 100,000 times before the State Department ordered their removal. The ensuing lawsuits led to a 2018 settlement, a 2021 Ninth Circuit decision vacating the injunction, and ongoing challenges to “ghost-gun” regulations. That history frames Manhattan Judge John Doe’s recent ruling allowing Luigi Mangione’s emotional-disturbance defense based on a seized 3D-printed handgun.
