Luigi Mangione, accused of murdering UnitedHealthcare CEO Brian Thompson, has secured the legal representation of Karen Friedman Agnifilo, a prominent New York lawyer and former CNN legal analyst. Ms. Agnifilo, a partner at Agnifilo Intrater LLP, brings extensive experience to the case, having previously served as the chief assistant district attorney in the Manhattan District Attorney's Office for seven years.

Ms. Agnifilo's spokesperson confirmed her involvement, highlighting her three decades of experience in criminal justice, specializing in both criminal defense and the prosecution of violent crimes, including complex homicides. Her background also includes work on civil and employment matters, Title IX cases, and internal investigations related to misconduct, discrimination, and sexual assault. During her tenure at the Manhattan DA’s office, she played a key role in establishing specialized units focused on human trafficking, hate crimes, antiquities trafficking, terrorism, and cybercrimes.

This development coincides with the emergence of new evidence in the case. Law enforcement has confirmed a match between the 3D-printed gun found in Mangione's possession upon his arrest and the shell casings recovered from the Manhattan crime scene. Fingerprint evidence further links Mangione to the scene. Currently held in Pennsylvania on gun-related charges, Mangione is contesting extradition to New York, although Manhattan District Attorney Alvin Bragg suggests he may waive extradition in the coming week. A Pennsylvania judge has denied Mangione bail, and he remains incarcerated at the Huntingdon State Correctional Institution.

In addition to the murder charge in New York, Mangione faces multiple charges in Pennsylvania, including carrying a firearm without a license, forgery, providing false identification to law enforcement, and possession of instruments of crime. New York prosecutors have also filed charges of illegal weapons possession and forgery. Pennsylvania District Attorney Peter Weeks has affirmed his commitment to facilitating Mangione's transfer to New York.

Mangione's Pennsylvania attorney, Thomas Dickey, maintains his client's innocence and anticipates a not guilty plea to all charges in both states. Police suggest Mangione's alleged motive stems from frustration with the health insurance industry and perceived corporate greed, though he was not a UnitedHealthcare member.
