BREAKING: Manifesto of UnitedHealthcare CEO murder suspect released: report

Mangione, per Klippenstein, who also published the mugshots, said he "wasn't working with anyone" and said that the "parasites had it coming." He references the American health care system, comprised primarily of private insurance companies, saying that it is the "most expensive" in the world but that American life expectancy is 42nd globally. This appears to be his reasoning for targeting UnitedHealthcare CEO Brian Thompson. UnitedHealthcare is the largest private insurer in the US.

Mangione was denied bail after his arrest.

The manifesto reads:

"To the Feds, I'll keep this short, because I do respect what you do for our country. To save you a lengthy investigation, I state plainly that I wasn't working with anyone. This was fairly trivial: some elementary social engineering, basic CAD, a lot of patience. The spiral notebook, if present, has some straggling notes and To Do lists that illuminate the gist of it.

"My tech is pretty locked down because I work in engineering so probably not much info there. I do apologize for any strife of traumas but it had to be done. Frankly, these parasites simply had it coming. A reminder: the US has the #1 most expensive healthcare system in the world, yet we rank roughly #42 in life expectancy.

"United is the [indecipherable] largest company in the US by market cap, behind only Apple, Google, Walmart. It has grown and grown, but [has] our life expectancy? No the reality is, these [indecipherable] have simply gotten too powerful, and they continue to abuse our country for immense profit because the American public has allwed them to get away with it. Obviously the problem is more complex, but I do not have space, and frankly I do not pretend to be the most qualified person to lay out the full argument.

"But many have illuminated the corruption and greed (e.g.: Rosenthal, Moore), decades ago and the problems simply remain. It is not an issue of awareness at this point, but clearly power games at play. Evidently I am the first to face it with such brutal honesty."

Klippenstein said that: "I’ve obtained a copy of suspected killer Luigi Mangione’s manifesto — the real one, not the forgery circulating online. Major media outlets are also in possession of the document but have refused to publish it and not even articulated a reason why. My queries to The New York Times, CNN and ABC to explain their rationale for withholding the manifesto, while gladly quoting from it selectively, have not been answered."
