Overview

• Defense attorneys filed a motion on June 3 asking Justice Gregory Carro to allow Luigi Mangione to attend his next New York state hearing without handcuffs or a bulletproof vest, arguing such measures prejudice his right to a fair trial.
• Prosecutors submitted new court filings on June 4–5 that include handwritten diary entries in which Mangione outlined months of ideological planning to assassinate UnitedHealthcare CEO Brian Thompson.
• The disclosed excerpts reveal Mangione surveilled Thompson the night before the December 4 shooting and planned to “wack the CEO at the annual investor conference” to protest what he called corporate greed.
• Assistant District Attorney Joel Seidemann told the court that shell casings marked “delay,” “deny,” and “depose” and subsequent threats against insurance executives demonstrate Mangione’s intent to intimidate the industry, supporting a terrorism enhancement to first-degree murder charges.
• In parallel federal proceedings, prosecutors are pursuing the death penalty for Mangione’s murder and stalking counts, while his defense continues to challenge the overlapping state and federal cases as unconstitutional double jeopardy.
