Defense resubmits motion to dismiss state charges against Luigi Mangione

Mangione entered a guilty plea on August 14th to federal charges connected to Thompson’s death, which occurred outside a Manhattan hotel on December 4, 2024. This plea came shortly before his scheduled state murder and weapons trial, initially set for September 8th.

Thompson’s death prompted a widespread search for the perpetrator and ignited criticism of the US healthcare industry.

Shortly after Mangione’s federal admission, his legal team filed a motion to dismiss the state case, arguing that New York’s double jeopardy laws prevent further prosecution.

While the US Constitution allows for both state and federal prosecution for the same crimes, New York state law stipulates that a person cannot be tried twice for the same offense or prosecuted separately for offenses stemming from the same act.

In the latest filing, Mangione’s lawyers maintain that the core actions in both the federal and state cases—the intent to kill and the subsequent killing of Brian Thompson—are identical. They argue that the federal stalking statute, intended to prevent murder, overlaps significantly with state murder laws.

Manhattan prosecutors are opposing the motion, asserting that the state proceedings can continue under an exception to the state’s double jeopardy rules. They contend that federal stalking charges and state murder offenses are distinct enough to avoid double jeopardy protections.

“Statutory double jeopardy applies only when a defendant has been ‘separately prosecuted’ for the same misconduct, and dismissed federal charges do not constitute a separate prosecution,” prosecutors stated.

Judge Gregory Carro, overseeing Mangione’s state case, has postponed further proceedings and scheduled a court date for December 10th.
