The mystery donor gave $36,500 to the defense fund earlier this week and explained the reasoning behind the move in an accompanying comment, noting that the response Mangione has gotten following his detainment played a large role in the donation.

“What intrigues me about this case is how unified folks' responses are regardless of strata,” the anonymous donor wrote. “In Corporate America, for instance, there has been widespread doubt of potential prosecutorial mishandling and overcharging.”

“I’ve also been surprised at the almost ubiquitous nature of support towards the suspect that I would expect to be quite bifurcated in this type of litigation,” they added. “Quite exceptional.”

The person’s donation beat out the previous highest donation of $30,000 made some time last month. The new top donation has increased the total raised for Mangione’s defense fund to over $722,000, bringing the total closer to the fund’s goal sum of $1 million.

Mangione’s federal murder charges could land him the death penalty, and he also faces state murder charges that accuse him of committing an act of terrorism. He has pleaded not guilty to the state charges but has not yet entered a plea on the federal charges.

He is currently being held at the Metropolitan Detention Center in Brooklyn, where he has received several letters and photos of support from the public. He addressed the supportin his first public statementlast month, saying that he was “overwhelmed” and “grateful” for those who have written to him in jail.

Mangione is scheduled to return to federal court in Manhattan on March 19.
