Luigi Mangione‘s bombshell diary entries have been released, revealing how he allegedly meticulously planned the assassination of UnitedHealthcare CEO Brian Thompson many months before the December shooting in the heart of Manhattan.
In shocking court documents, filed Wednesday, prosecutors revealed that Mangione was in possession of a red notebook diary when he was arrested at a McDonald’s in Altoona, Pennsylvania, at the end of a five-day manhunt.
The diary documented Mangione’s plot for the murder and his musings about how his plan would gain greater support than the actions of the Unabomber, the documents say.
‘So say you want to rebel against the deadly, greed fueled health insurance cartel. Do you bomb the HQ? No. Bombs=terrorism,’ he allegedly wrote in August 2024.
‘Such actions appear the unjustified anger of someone who simply got sick/had bad luck and took their frustration out on the insurance industry, while recklessly endangering countless employees.’
Instead he wrote of plans to ‘wack’ the CEO of the healthcare giant at ‘parasitic bean-counter convention’ as it ‘doesn’t risk innocents… The point is made in the news headline ‘Insurance CEO killed at annual investors conference.’’

The same diary entry appears to suggest Mangione had previously considered a different target – detailed as ‘KMD’ – before deciding upon UnitedHealthcare, and its CEO.
‘KMD would have been an unjustified catastrophe,’ he writes.
In another scrawling handwritten note shared in the new court filing, Mangione apologizes to the federal agents hunting for him.
Despite his alleged confession, the 27-year-old has pleaded not guilty to both state and federal charges in connection with the December murder.
