A new court filing details Luigi Mangione's diary entries in the months leading up to the killing of UnitedHealthcare CEO Brian Thompson, shedding light on how the murder suspect allegedly targeted the executive after initially planning a larger bombing attack.
The previously unreported entries were made public on June 4 in a filing by the Manhattan District Attorney's Office, which was submitted in response to a motion by Mangione's defense team seeking to stay or dismiss the New York state case against him.
"I finally feel confident about what I will do. The details are coming together. And I don't feel any doubt about whether it's right/justified," Mangione wrote in an entry dated Aug. 15, 2024, according to court records. "I'm glad-in a way-that I've procrastinated bc [sic] it allowed me to learn more about (UnitedHealthcare)," which he later describes as a company "that literally extracts human life force for money."
The writings go on to say that an attack Mangione initially planned would have been "an unjustified catastrophe," which would "do nothing to spread awareness/improve people's lives."
He added, "The target is insurance. It checks every box."
