Luigi Mangione manifesto goes viral exposing frustrations with healthcare and corporate America

A 26-year-old named Luigi Mangione was taken into custody on December 9, 2024, as a "strong person of interest" in the murder of UnitedHealthcare CEO Brian Thompson. Mangione was apprehended at a McDonald's in Altoona, Pennsylvania, in connection to Thompson's fatal shooting in New York.  

Authorities revealed to the media after the arrest that Luigi carried a handwritten manifesto. The manifesto allegedly detailed his frustrations with the healthcare industry and corporate America. According to an officer who spoke to CNN, the document included the phrase, "the parasites had it coming." NYPD Chief of Detectives Joseph Kenny stated that the manifesto showcased Mangione's "ill will toward corporate America," as reported by Reuters.  

The manifesto, purportedly written by Mangione and titled The Allopathic Complex and Its Consequences, has been widely shared on social media. Published on Substack by a user named LM Publication, the document also bore the subtitle, "Luigi Mangione’s last words," and was dated December 9, 2024.  

The widely circulated manifesto claimed that Mangione's mother was diagnosed with "severe neuropathy" at the age of 41. It stated that she believed her symptoms began a decade earlier, starting with "burning sensations in her feet and occasional sharp stabbing pains."  

“At first, the pain would last a few moments, then fade to tingling, then numbness, then fade to nothing a few days later,” the document read.  

The manifesto alleged that the initial two doctors misdiagnosed Luigi’s mother, attributing her condition to psychosomatic issues or a compressed spinal nerve. These doctors reportedly recommended rest, sleep, exercise, and eventually back surgery. A third doctor later performed additional tests, including a Nerve Conduction Study, MRI, and Electromyography.  

According to the document, these tests ranged in cost from $800 to $1200, and Luigi’s mother "hit the $6000 deductible of her UnitedHealthcare plan in October."  

“Then the doctor went on vacation, and my mother wasn’t able to resume tests until January when her deductible reset,” it added.  

The manifesto further accused Brian Thompson’s company of restricting specialist visits to twice a year. It also alleged that UnitedHealthcare “constantly changed their claim filing procedure,” among other grievances.
