Luigi Mangione Prosecutors Accused of Gaining Access to Medical Records

The Manhattan District Attorney’s Office fraudulently gained access to Luigi Mangione‘s private medical records, the accused CEO killer’s lawyers claimed in a bombshell filing on Thursday, July 17.

Mangione’s counsel, Karen Friedman Agnifilo, Marc Agnifilo and Jacob Kaplan, alleged in court documents obtained by Us Weekly that Assistant D.A. Joel Seidemann “drafted and signed” a subpoena to Aetna on May 14 demanding a representative for the health insurance company “mail or deliver” the 27-year-old’s account number and coverage timeline ahead of a May 23 hearing.

However, the attorneys pointed out, “There was never a court proceeding scheduled for May 23, 2025, nor was there ever a court appearance scheduled for the entire month of May.” They called it a “completely made-up date” that was not approved by any party.

“By reaching a secret arrangement to have Aetna send the information to the District Attorney directly, and not to the Court, the District Attorney ensured that the confidential, HIPAA protected, doctor-patient privileged information was not subject to challenge by the defense,” the motion read, referring to the Health Insurance Portability and Accountability Act.

Ultimately, Aetna emailed “over 120 pages of material” to the D.A. outlining Mangione’s “different diagnoses” that were “not relevant” to the case, according to his lawyers, who requested sanctions and a “full evidentiary hearing with sworn testimony by all people with knowledge of how the subpoena was drafted, how Aetna was directed to provide this information to the District Attorney, instead of the Court, who reviewed the protected materials, who was told about the protected materials and who supervised this process.”

The legal team also stated in their filing that they reserve “the right to seek various remedies, including the recusal of the prosecution team, suppression of evidence or dismissal of the indictment” against their client.

A spokesperson for the Manhattan D.A.’s Office confirms to Us that it had “requested very limited information from Aetna,” which sent “additional materials in error.”

“We deleted the materials as soon as we became aware of them and brought it to defense and the court’s attention,” the office claims, adding that it will formally respond in its own court filing.

This is not the first time that prosecutors have been accused of improperly using Mangione’s private information. His counsel previously claimed that a paralegal had eavesdropped on an 11-minute jailhouse phone call between Mangione and Friedman Agnifilo in April. They also called out the D.A.’s Office for failing to redact his social security number, driver’s license number, cellphone number and a prior address in legal filings between April and June.

In response, prosecutors explained in court documents at the time, “Consistent with well-known practice in federal and state jails, many of the defendant’s calls are recorded with notice of the recording provided to him and the person on the other side of any calls.” They acknowledged that a paralegal had inadvertently listened to a call between Mangione and Friedman Agnifilo but stopped upon realizing that a lawyer was on the line.

Mangione was arrested in December 2024 for the fatal shooting of UnitedHealthcare chief executive Brian Thompson in New York City earlier that month. A federal complaint alleged that the Ivy League graduate had expressed “hostility toward the health insurance industry and wealthy executives in particular” prior to the incident.

Mangione was indicted on 11 state charges and four federal charges, including first-degree murder and stalking. He has pleaded not guilty. Federal prosecutors are seeking the death penalty.
