Friends and colleagues struggle to cope with the UnitedHealth executive’s death, while others cheer for the man accused of killing him.

Mangione, 26, is expected to be turned over to the NYPD by federal agents in the morning and brought into state court for his arraignment on murder charges.

In an entry in the notebook dated Aug. 15, Mangione allegedly wrote he “was glad” that he procrastinated in his preparations because it “allowed him to learn more” about UHC.

A former colleague told Newsweek he had "little doubt" Thompson would have ascended to the top of the company "had his life not ended so tragically."

Horrified colleagues and friends say the online caricature of Brian Thompson in the wake of his murder bears no resemblance to the Iowa native they knew.

A video shared online of Alpha Studio venture capitalist Brian Thompson speaking at a 2012 entrepreneurs’ workshop is miscaptioned as showing UnitedHealthcare CEO Brian Thompson talking about “working with” former House speaker Nancy Pelosi.

The contrast in how Penny and Mangione have been covered in the media and treated by the elite show that vigilante violence actually is acceptable in America when carried out against those with little to no agency.
