Overview

• The defense contends veteran prosecutor Joel Seidemann misled Aetna into handing over Mangione’s entire medical file by fabricating a court date and issuing a fraudulent subpoena.
• Mangione’s attorneys have asked Justice Gregory Carro to impose sanctions, hold a full evidentiary hearing on alleged HIPAA violations and compel disclosure of all Aetna–DA communications related to the subpoena.
• The Manhattan DA’s office maintains it requested only Mangione’s account number and coverage period, deleted the extra 120 pages upon realizing the error and notified both the defense and the court.
• This dispute adds to a string of pretrial battles in the high-profile case, which have included motions to suppress evidence, challenges to warrantless searches and claims of improper eavesdropping on attorney–client calls.
• Luigi Mangione has pleaded not guilty to state terrorism enhancements and federal murder and stalking charges in the December killing of UnitedHealthcare CEO Brian Thompson, with prosecutors seeking the death penalty federally.
