LUIGI MANGIONE SHOULD STAND TRIAL IN NEW YORK STATE COURT—HIS FEDERAL STALKING CONVICTIONS SHOULD NOT BAR THE STATE SECOND-DEGREE MURDER CASE FROM PROCEEDING
INTRODUCTION AND BACKGROUND
On Friday, August 14th, Mangione pleaded guilty to two counts of a federal indictment alleging stalking and cyberstalking which resulted in the death of United Healthcare CEO Brian Thompson. The federal charges include the possibility of life in prison. He is to be sentenced in December after the preparation of a sentencing report. This indictment or criminal federal complaint was issued only two weeks after the homicide by then-Attorney General Merrick Garland through the United States Attorney’s Office for the Southern District of New York. It is attached HERE. The original federal complaint also charged murder and use of a firearm in the commission of murder. In counterintuitive reasoning that even the federal court acknowledged, the federal murder and firearms charges were dismissed. The federal court held in January 2026 that the stalking and cyberstalking offenses were not “crimes of violence” at their core and could not serve as a predicate for a federal murder charge, which is very limited and which charges are generally reserved to the states. Federal murder charges must be predicated upon proof beyond a reasonable doubt that the charged murder was committed during and in relation to a different federal crime, which must be a “crime of violence.” A “crime of violence” is defined under federal law as one that has as an element, the use, attempted use, or threatened use of physical force against the person or property of another. Acknowledging that it was bound by precedent, the federal court looked at the core elements of the stalking statutes and held that they are not “crimes of violence” at their core and could not serve as predicates for the murder charge or the firearms charge. This is an important finding, however unsatisfying, that creates an elemental distinction between the state and federal charges and which should allow the state murder case to proceed. There should be no question that the New York murder charge IS a crime of violence with different elements.
THE CHARGES AT ISSUE CURRENTLY
Mangione was also charged pursuant to New York’s criminal code with various offenses which included First-Degree Murder with the aggravating factor of terrorism, which would elevate it, as well as Second-Degree Murder (Intentional). In September 2025, the state judge dismissed the First-Degree Murder charge finding that the aggravating factor of terrorism was lacking. His Order is attached HERE. Trial is currently scheduled for September 8th in New York County on the remaining Second-Degree Murder charge which is an A-1 Felony and carries the potential of life in a state prison. Mangione’s defense team, irresponsibly calling him a “victim” of dual prosecutions, plans to use the “jeopardy” of the guilty finding to bar a second finding in the state case based upon New York’s “double jeopardy” law, CPL 40.20, which will be discussed below. Broadly viewed, this provision is an exception to the general rule that prosecutions by dual sovereigns, federal and state, for even the same or similar conduct are not generally violative of most state or the United States Constitutions. New York provides greater protection, and the statute recognizes that where the two prosecutions arise from the same criminal act or transaction, the case may be subject to dismissal. However, the statute carries forward well-settled law from the United States Supreme Court as an exception in what is known as the “Blockburger” test, also discussed below. This arises when the two offenses contain elements of proof that are different and the two offenses target different evils. The federal court already laid out the roadmap for a finding that jeopardy has not attached with the federal pleas.
The swift federal indictment, skillfully steered into the guilty pleas to just the stalking offenses, was an obvious shot across the bow of the feckless Alvin Bragg, who goes after Daniel Penny for homicide but who has an abysmal conviction rate and tries cases in front of juries that might be replete with Mangione fans. A horrible but real concern. In addition, this indictment vindicated the federal interest in deterring interstate stalking and the use of electronic means to advance a criminal plan and course of conduct resulting in death. Mangione’s actions violated these purely federal interests, and he should face the state prosecution. Expect a delay as Bragg fumbles and the matter is appealed if the court dismisses the state case. In the meantime, this miscreant will be where he belongs.
THE FACTS
This is an excerpt from the DOJ press release which was issued on December 19th, 2024, in connection with the filing of the federal charges:
Over the course of the last several months, MANGIONE meticulously planned the execution of Brian Thompson in an effort to initiate a public discussion about the healthcare industry. MANGIONE targeted the victim, tracked his whereabouts, and traveled from out of state to New York City, where the victim was scheduled to attend the company’s investor conference. After arriving in the City on November 24, 2024, more than one week before the murder, MANGIONE performed reconnaissance in the area around the victim’s hotel and the conference venue where the victim was scheduled to speak. Using a false identification, MANGIONE checked into an Upper West Side hostel.
In the early morning hours of December 4, 2024, MANGIONE traveled by bicycle from the Upper West Side to the area around West 54th Street and Sixth Avenue. At approximately 6:45 a.m., MANGIONE strategically placed himself in between two cars on West 54th Street, and as the victim passed by, MANGIONE walked up behind the victim and fired several gunshots from a 9mm pistol, causing the victim’s death. The pistol was equipped with what appeared to be a firearm sound suppressor or silencer. After the murder, MANGIONE fled on his bicycle northbound through Central Park and ultimately back to the Upper West Side.
On December 9, 2024, MANGIONE was arrested in Altoona, Pennsylvania, while he sat in a fast-food restaurant after being recognized by one of the restaurant’s workers. Members of the Altoona Police Department confronted MANGIONE, who provided the same false identification that he used when checking in to the Upper West Side hostel. MANGIONE was also found in possession of, among other things, a 9mm pistol and a sound suppressor consistent with the weapon used to kill the victim.
This was included as part of another DOJ press release on August 14th after the guilty pleas:
MANGIONE, 28, of Maryland, pled guilty to one count of interstate stalking resulting in death, which carries a maximum potential sentence of life in prison, and one count of cyberstalking through use of interstate facilities resulting in death, which carries a maximum potential sentence of life in prison…
THE STATUTES IMPLICATE DIFFERENT ELEMENTS AND TARGET DIFFERENT CRIMINAL ACTS
CPL 40.20, New York’s statutory double jeopardy provision, generally prohibits successive prosecutions for two offenses based on a single act or criminal transaction. One of the exceptions to the statutory bar permits sequential prosecutions for offenses arising from the same criminal transaction if each of the offenses as defined contains an element which is not an element of the other, and the statutory provisions defining such offenses are designed to prevent very different kinds of harm or evil. The first prong of the exception under CPL 40.20(2)(b) thus requires a comparison of the Federal and State charges at issue to determine whether each of the Federal offenses contains an element which is not an element of any State offense, and vice versa. This was the rule set forth by the New York Court of Appeals, the state’s highest court in People v. Bryant, a 1998 case.
This is the New York charge:
§ 125.25 Murder in the second degree.
A person is guilty of murder in the second degree when:
1. With intent to cause the death of another person, he causes the
death of such person or of a third person…
The federal charges for which Mangione now stands guilty and to which he knowingly pled arise under 18 U.S.C. 2261A and (b). The gravamen of these charges have concisely been set forth at federalcriminalattorneys.com and appears below:
Under 18 U.S.C. 2261A, a person is guilty of stalking when they travel across state lines or into federal jurisdiction, including maritime boundaries or Indian territory, with the intent to kill, injure, harass, intimidate, or place another person in fear of death or physical injury.
This statute also covers mail or electronic communication threats, including phone, email, and social media posts.
Specifically, 18 U.S.C. 2261A affords a comprehensive range of behaviors considered stalking. These include the following:
- Acting with the intention to kill, injure, harass, or intimidate the victim. Note the wide span between “kill” and “intimidate”—both are treated equally under federal law;
- Placing the victim under surveillance with intent to kill, injure, harass, or intimidate them;
- Engaging in a “course of conduct” that causes the victim to be in reasonable fear of death or serious bodily injury to themselves, their spouse/partner, an immediate family member, or that person’s pet, service animal, or horse;
- Causing or attempting to cause substantial emotional distress to the victim or acting in a way that would be reasonably expected to do so.
Other things to know about this law:
- To be convicted of federal stalking, federal prosecutors must demonstrate that you are engaged in a course of conduct. In other words, stalking is a pattern of behavior, not a single incident of harassment;
- Course of conduct. The term “course of conduct” means a pattern of conduct composed of 2 or more acts, evidencing a continuity of purpose.
Each of the offenses charged in the state and federal indictments requires proof of different elements. Although the result in both is homicide, the offenses are distinct. The federal crimes are not crimes of violence; the state crime is. The applicable rule is that where the same act or transaction constitutes a violation of two distinct statutory provisions, the test to be applied to determine whether there are two offenses or only one is whether each provision requires proof of a fact which the other does not. A single act may be an offense against two statutes; and if each statute requires proof of an additional fact which the other does not, an acquittal or conviction under either statute does not exempt the defendant from prosecution and punishment under the other. This is the test the New York State Court will use as set forth in Blockburger v. United States, 284 U.S. 299 (1932). The federal statute requires elements and captures conduct engaged in by Mangione which involves elements of proof legally and factually distinct from the simple state murder charge. These are the following:
- State lines must be crossed to engage in the criminal scheme—this is a purely federal interest;
- There must be a course of conduct alleged and proved that includes at least two distinct acts;
- There must be alleged and proved the use of an electronic communication system of interstate commerce and a facility of interstate or foreign commerce in the furtherance of criminal design.
Mangione traveled across state lines and only found the location of the United Health investors conference by using electronic means to pose as an investor and used facilities of interstate commerce to get to the scene of the cowardly and heinous act. New York prosecutors need not show any of this as an element of the simple Second-Degree Murder charge and need only prove that he “caused the death” of Thompson. The case was perfected for New York purposes when Mangione showed up on West 54th Street in Manhattan and shot an unarmed man in the back for no reason other than a misguided personal grievance.
CONCLUSION
The state case should proceed. The different statutes implicate different acts and public policies. I hope that the New York courts see this and vindicate the ability of this sovereign to bring Mangione to justice regardless of what he faces in a federal forum. This is the right result.
