Luigi Mangione's state murder trial, scheduled to start on September 8, has been postponed indefinitely due to his guilty plea last week to federal charges related to the stalking and fatal shooting of UnitedHealthcare CEO Brian Thompson in 2024. Mangione's attorneys argue that he is being double charged for the same "criminal transaction" and are seeking to have the state case thrown out on double jeopardy grounds. The judge has given the Manhattan District Attorney's office until October 9 to respond to the defense's claims, with a hearing scheduled for December 10. Federal prosecutors are seeking life in prison when Mangione is sentenced on December 18, but federal sentencing guidelines call for a term of 24-30 years.

Story summary
Here is a summary of the news story:
Luigi Mangione, 28, has pleaded guilty to two federal charges of stalking with the intent to kill Brian Thompson, the CEO of UnitedHealthcare, who was fatally shot on a Manhattan street in December 2024. Mangione's lawyers had been meeting with federal prosecutors to discuss a potential plea deal, but he entered his guilty plea without one. The guilty plea will likely avoid a federal trial, but it does not guarantee leniency at sentencing. In addition to the federal charges, Mangione also faces state murder charges in connection with Thompson's death. His lawyers have now asked that the state case be thrown out due to double jeopardy grounds, and a hearing on this matter is scheduled for 10 December.
