Overview

• Mohn was sentenced to life in prison without possibility of parole, the maximum penalty under Pennsylvania law.
• The conviction stemmed from his January 30, 2024 killing of Michael F. Mohn, which Mohn livestreamed in a graphic 14-minute YouTube video.
• Prosecutors presented evidence of years-long conspiracy-driven writings, notebook entries listing “Boom” and “Slice” as backup plans, and bomb-making instructions found on a seized USB device.
• Michael Mohn had served two decades as a civil engineer with the U.S. Army Corps of Engineers, and prosecutors argued the killing was intended to intimidate federal workers.
• Mohn has indicated he will appeal his sentence, challenging both the terrorism statute application and earlier competency determinations.
