Overview

• Defense attorneys allege Assistant DA Joel Seidemann misled Aetna into producing Mangione’s full medical file after requesting only his account number and coverage period
• The subpoena cited a fictitious May 23 court date and was signed by prosecutors rather than a judge, bypassing judicial oversight and breaching doctor-patient privilege
• Manhattan DA’s office maintains it requested minimal information, deleted the excess records upon learning of the error and informed both defense counsel and the court
• The defense motion asks for sanctions against prosecutors, a full evidentiary hearing with sworn testimony and access to all communications between Aetna and the DA’s office
• Mangione remains charged with state terrorism-related murder counts and federal murder and stalking charges with the death penalty sought, next appearing in state court on Sept. 16, 2025
