Ex-Manhattan Prosecutor Joins Mangione’s High-Profile Legal Battle

Luigi Mangione Secures Top Legal Defense Amid Murder Charge

Luigi Mangione has enlisted Karen Friedman Agnifilo, a prominent New York attorney, to defend him against a second-degree murder charge in the death of UnitedHealthcare CEO Brian Thompson, CNN has learned.

Who Is Karen Friedman Agnifilo?

Friedman Agnifilo, a former chief assistant district attorney in Manhattan under Cyrus Vance Jr., brings years of experience navigating New York’s criminal justice system. She has been in private practice since 2021 and is known for her deep familiarity with state courts. A veteran prosecutor described her as “knowing every corridor, every judge, every clerk in the courthouse.” Friedman Agnifilo, who has also served as a CNN legal analyst, has declined to comment on the case.

Key Evidence Against Mangione

Authorities have presented significant evidence linking Mangione to the crime. The 3D-printed gun found on him during his arrest matches the three shell casings discovered at the Midtown Manhattan crime scene. Additionally, his fingerprints were found on items near the scene.

Mangione is currently in custody in Pennsylvania, facing gun-related charges while fighting extradition to New York. However, Manhattan District Attorney Alvin Bragg indicated that Mangione “may waive” his extradition next week.

Legal Proceedings in Pennsylvania

Pennsylvania state Judge Dave Consiglio has denied Mangione bail, keeping him detained at the Huntingdon State Correctional Institution. Mangione’s attorney in Pennsylvania, Thomas Dickey, has denied his client’s involvement in the New York killing and plans to plead not guilty to both the murder charge and related gun and fake ID charges in Pennsylvania.

The court has allowed Mangione 14 days to file for a writ of habeas corpus, which would require authorities to justify his detention. Simultaneously, Pennsylvania prosecutors have 30 days to secure a governor’s warrant. Both New York Gov. Kathy Hochul and Pennsylvania Gov. Josh Shapiro have expressed readiness to expedite the process.

Motive and NYPD Findings

An NYPD intelligence report suggests that Mangione’s actions were driven by anger toward the health insurance industry and “corporate greed.” Investigators uncovered a handwritten “manifesto” in which Mangione described the killing as a symbolic act against alleged corruption. The three-page “claim of responsibility,” along with a spiral notebook containing his writings, is being analyzed as evidence.

According to the NYPD report, Mangione viewed the act as a “symbolic takedown” and a challenge to the power structures he believed were complicit in corruption.

Funding Mangione’s Defense

It remains unclear who is funding Mangione’s legal defense. While Dickey declined to comment on whether Mangione’s prominent Baltimore family is covering the costs, he mentioned that members of the public have offered to contribute. Friedman Agnifilo’s representative also declined to comment on the matter.

What Happens Next?

Blair County District Attorney Peter Weeks has stated his office’s readiness to ensure Mangione’s extradition to New York. Once there, Mangione is expected to plead not guilty to the murder charge and other related counts. The case’s next steps will depend on the outcomes of the legal proceedings in Pennsylvania and the eventual trial in New York.
