This unusual situation meant that as internet sleuths worked to discover as much information about him as possible, platforms such as YouTube and Instagram were working to shut down his accounts. X initially shut down Maglione’s account, but after CEO Elon Musk said he was “looking into it” the account was restored
Google was also forced to remove reviews of the McDonald’s where Mangione was identified on Monday, after Mangione supporters review-bombed it with negative comments and one-star reviews.
Before his identity was revealed on Monday, his online supporters, primarily on TikTok, Bluesky, and X, had created an entire fictionalized version of the shooter as a left-wing revolutionary hero who was standing up for the millions of Americans whose lives have been impacted negatively by interactions with the healthcare system.
Videos glorifying the killer flooded TikTok, while one person decided to get a tattoo of the alleged shooter’s face. In Washington Square Park in New York City, a lookalike competition was held on Saturday.
Indeed, “Deny, Defend, Depose,” which is widely viewed as a pointed critique of the health insurance industry in America, has become a rallying cry online in recent days as the focus moved away from the shooting itself and onto the shooter and his motives.
However, the fictionalized version of the shooter that was created online does not match reality. Mangione, who allegedly had a handwritten manifesto admitting to the killing in his possession when arrested, is a software engineer from a privileged background. He also follows popular right-wing influencers, such as Tucker Carlson, Joe Rogan, and Jordan Peterson—though he has also criticized some of the arguments put forward by these figures.
During a brief court appearance on Monday night, the police did not outline a motive for the shooting, but based on Mangione’s online posts and reading lists, it appears that the pain from an injury suffered while surfing could have played a significant part in his motivation.
Despite Mangione not fitting the idealized hero that many online created in the time between the shooting and his arrest, the alleged shooter’s fans have continued to post fan fiction about him.
On Archive of Our Own, a repository of fan fiction, half a dozen pieces of prose about Mangione were posted in the hours after he was identified. In one piece entitled “McGuire Road Designated Dispersed Campsite,” an author with the username basedIdiot imagines Mangione and another man on a road trip trying to escape from New York. “‘Oh, am I not your beloved?’ Luigi Mangione mockingly fainted into the other man’s arms,” the author wrote.
