Court: New York Supreme Court, New York County (Criminal Term, Part 32)
Judge: Justice Gregory Carro
On Calendar

• Terrorism Count Challenge
  Defense seeks dismissal of New York’s murder as an act of terrorism charge as vague and overlapping with federal case; prosecution argues Mangione’s writings show intent to intimidate an industry.
• Suppression of Arrest Evidence
  Defense moves to suppress a handgun and notebook/diary seized at arrest; prosecution insists items were lawfully obtained and are central to motive/intent.
• Psychiatric-Defense Timing Fight
  Prosecution says defense missed the Aug. 25 deadline to file notice of psychiatric defense; defense requests extension; judge may rule immediately or order briefing.
• HIPAA / Aetna Records Dispute
  Defense claims DA improperly obtained Mangione’s medical records; seeks sanctions or suppression. Prosecution says request was narrow and Aetna overproduced. Court may set evidentiary hearing or impose limits.

10:00 AM: Ruling

• New York Supreme Court Justice Gregory Carro dismissed two of the top state charges against Mangione: first-degree murder and second-degree murder, both framed as acts of terrorism. He found them legally insufficient under state terrorism law.
• The judge held that while Mangione’s writings and statements show ideological motive and animus toward the health insurance industry, they do not rise to the legal requirement under New York’s terrorism statute—specifically, there was insufficient evidence that Mangione intended to “intimidate or coerce a civilian population.
• The state still has a second-degree murder charge (intentional) pending against Mangione.
• There are other state charges (weapons, etc.) and the parallel federal prosecution, where Mangione is also charged, and where he could face the death penalty.
