NEW YORK – The trial of Luigi Mangione, accused of murdering UnitedHealthcare CEO Brian Thompson, has been postponed indefinitely. Originally scheduled to start on September 8, 2023, the delay comes as Mangione’s lawyers seek to dismiss the state case based on double jeopardy after he entered a guilty plea to federal charges.
Judge Gregory Carro issued an order canceling the trial, giving the Manhattan District Attorney’s office until October 9, 2023, to respond to the defense’s claims. A hearing is set for December 10, just before Mangione is scheduled to be sentenced for his federal crimes.
Mangione, 28, pleaded guilty to two stalking charges in a Manhattan federal court. He admitted to following Thompson to an investor conference and fatally shooting him outside a hotel on December 4, 2024. Federal prosecutors indicated they would seek a life sentence, although federal guidelines suggest a sentence of 24 to 30 years.
During his guilty plea, Mangione stated, “On the morning of December 4, 2024, I shot Mr. Thompson in Manhattan, and he died.” Following this, his legal team filed documents asking for the state murder charge to be thrown out, arguing that he is being punished twice for the same actions. They described him as a “pawn in parallel prosecutions.”
In the state case, Mangione has pleaded not guilty to the charges, which could also result in a life sentence if he is convicted. The Manhattan District Attorney’s office, led by Alvin Bragg, has stated they will oppose any attempt to dismiss the state charges, especially since Mangione’s federal sentence has not yet been determined.
New York has strict double jeopardy protections, which can prevent a state prosecution if a federal case involving the same actions results in a guilty plea or a jury is sworn in. Judge Carro will ultimately decide whether these protections apply to Mangione’s situation, but any ruling can be appealed.
In his federal case, Mangione was charged with traveling across state lines to stalk and kill Thompson, utilizing various methods including a cellphone and the internet to plan the attack. His lawyers argue that the actions he took to stalk Thompson are intrinsically linked to the murder, claiming that they are part of the same criminal transaction.
Assistant District Attorney Joel Seidemann has countered that the state charges entail different legal elements and should not be dismissed based on the federal guilty plea. He emphasized the importance of the state’s interest in prosecuting serious offenses like murder, which reflect the value of human life.
