Luigi Mangione, the suspect accused of killing UnitedHealthcare CEO Brian Thompson in Manhattan on Dec. 4, 2024, has accepted nearly $300,000 in donations for his criminal defense.

Mangione is charged with first-degree murder in furtherance of an act of terrorism, stalking and a slew of other state and federal charges in both New York and Pennsylvania, for allegedly gunning down Thompson, a married father of two from Minnesota.

“Luigi is aware of the fund and very much appreciates the outpouring of support. My client plans on utilizing it to fight all three of the unprecedented cases against him,” Karen Friedman Agnifilo, Mangione’s lead defense attorney, said in a Monday statement, according to the December 4 Legal Committee, which created the fund.

The fundraiser garnered more than $290,000 from more than 10,000 individual donations, according to a press release.

Police found a manifesto on the suspect when he was arrested days later in Altoona, Pennsylvania, where he traveled by bus from New York after the alleged killing.

“Luigi Mangione allegedly conducted the carefully premeditated and targeted execution of Brian Thompson to incite national debates,” James Dennehy, assistant director in charge of the FBI’s New York field office, said in a statement after Mangione’s extradition to New York. “This alleged plot demonstrates a cavalier attitude towards humanity — deeming murder an appropriate recourse to satiate personal grievances.”

The 26-year-old Mangione is originally from Maryland and has recently lived in California and Hawaii. He graduated valedictorian from the Gilman School, a private, all-boys high school in Baltimore, in 2016. Mangione went on to receive his bachelor’s and master’s degrees in computer science from the University of Pennsylvania in 2020.
