Complicity in homicide raises a question that can radically change the meaning of an accusation: can someone who did not materially cause the death still be held liable for it? The answer does not depend solely on whether multiple people were present or involved in the same incident. What matters is the contribution made by each individual, what each person intended to achieve, and the relationship between that conduct and the fatal event.
I will discuss the differences between complicity in intentional homicide, preterintentional homicide, and complicity in a more serious crime committed by another participant. I want to clarify why passive presence does not automatically equal participation, why the intent to strike does not always coincide with the intent to kill, and which facts help distinguish a full charge from a different liability.
Complicity does not coincide with mere presence
Being at the scene is not enough. Article 110 of the Italian penal code extends the penalty provided for an offence to anyone who participates in its commission, but it requires effective participation in the act. The contribution can be material, such as holding the victim down or providing a tool used in the assault, or moral, such as knowingly determining or reinforcing another person's criminal decision. The starting point remains the current text of the penal code.
The contribution must have a concrete meaning. Anyone who creates an obstacle to escape, indicates where the assaulted person is, or keeps watch to allow another's action may assume a role in the event. It is different to witness without intervening, to be casually in the vicinity, or to have personal relationships with the perpetrator: these circumstances can be examined in the trial, but they do not replace the proof of participatory and conscious conduct.
Each position remains individual. It is not necessary for everyone to perform the same act nor for each person to directly cause the fatal injury. However, to attribute homicide to a co-participant, it is necessary to link their action or contribution to the fact carried out by the others and to ascertain what result they intended to help produce. Liability does not stem from simple membership in a group.
When complicity involves intentional homicide
In intentional homicide, death falls within the intended act. Article 575 of the Italian penal code governs homicide and provides for a prison sentence of no less than twenty-one years in its basic form. If multiple people act in complicity, the decisive question is not only who inflicted the final blow: it must be verified whether each co-participant acted knowing and wanting to contribute to causing death. The regulatory reference is in the current penal code.
It is not necessary for everyone to perform the lethal act
The executive conduct can be divided. One person may immobilize the victim, another strike them, and a third prevent them from receiving help. This division of roles does not automatically make the liabilities identical, but it does not exclude complicity in homicide if the actions are part of a common action directed towards death. The judge must assess the actual contribution, the awareness of the project, and the link between the conduct and the event.
Intent is inferred from proven facts. Words uttered before or during the incident, the modalities of the assault, the instruments used, the repetition of blows, interventions to obstruct rescue, and subsequent conduct can be relevant as items of proof. However, no isolated datum resolves the issue: a heated phrase, mere proximity, or silence in itself does not necessarily demonstrate that death was shared and desired.
Preterintentional homicide: when beatings or injuries are intended, not death
Preterintentional homicide has more specific prerequisites. Article 584 of the Italian penal code concerns anyone who, by committing acts directed at committing beatings or personal injuries, causes a person's death. The penalty provided by the provision is imprisonment from ten to eighteen years. It is therefore not a simple formula for any death occurring during a fight: both intent regarding the beatings or injuries and the causal link between that conduct and the demise are required.
Death must not be intended. If the intent to kill is proven, the qualification to be examined is intentional homicide, not preterintentional homicide. If instead the action is directed at striking or injuring and the victim dies, the concrete dynamics, the victim's conditions, the type of violence exercised, and the development of the event become central. A recent overview by the Court of Cassation recalls the need to concretely assess the predictability of the mortal outcome in framing the psychological element of preterintentional homicide: penal overview of the Court of Cassation, November 2025.
In complicity, the object of the agreement also matters. Multiple people can be held liable for preterintentional homicide when they knowingly participate in an assault directed at beating or injuring, and the demise derives from that conduct. However, it is not sufficient to have reached the place together with the others or to have had a role unrelated to the violence. It is necessary to distinguish who takes part in the aggressive action from who does not adhere to it or does not provide a causally significant contribution.
A more serious crime committed by a co-participant: anomalous complicity
Article 116 concerns a fact different from the intended one. It can happen that multiple people agree on a less serious crime and that one of the participants commits a different or more serious offence, including a homicide. In this hypothesis, it is not correct to presume that everyone wanted the more serious fact. The provision requires ascertaining whether the event derives from the co-participant's conduct and whether it fell within the concretely foreseeable development of the common action.
Foreseeing is not the same as accepting. The Constitutional Court has clarified that liability under Article 116 also requires a subjective element: the different or more serious crime must be capable of presenting itself, in the circumstances of the case, as a foreseeable development of the intended one. The same Court distinguishes this situation from eventual intent: if the co-participant foresees the more serious event and accepts its risk, the position may be that of full liability for the intended or accepted crime. The principle is illustrated in the judgment of the Constitutional Court no. 55 of 2021.
The reduction of penalty is not automatic. The second paragraph of Article 116 provides for a decrease for those who intended the less serious crime when the one committed by the other co-participant is more serious. Before discussing the measure of the penalty, however, it is necessary to establish whether the prerequisites of anomalous complicity truly exist: a contribution to the initial conduct, the link with the further fact, and the concrete predictability of the evolution. Merely stating "I did not want to kill" does not close this assessment.
Facts that distinguish individual liabilities
The reconstruction must separate the conducts. In an incident involving multiple people, the accusation cannot confuse roles into a single indistinct description. Relevant elements include who started the assault, who continued after a change in situation, who materially facilitated the action, who could understand the use of a weapon, and whether there were autonomous initiatives compared to what was agreed.
The causal link is not a technical detail. It is necessary to understand whether death derives from the contested conducts and in what way. Medical-legal reports, images, messages, testimonies, and traces at the scene can help reconstruct times, the violence employed, each person's interventions, and rescue possibilities. A piece of proof can clarify the materiality of the incident without demonstrating, by itself, that a certain co-participant wanted death or could foresee another's further action.
A minimal contribution can affect the penalty, not cancel the crime. Article 114 of the Italian penal code allows the judge to decrease the penalty when a co-participant's contribution to the preparation or execution of the crime was of minimal importance. It is not an automatic rule and does not transform an effective contribution into irrelevance. The distinction is important: first, it is ascertained whether complicity exists; only afterwards is it assessed whether the role has a mitigated weight in determining the sentencing treatment.
How to navigate a charge
The legal qualification can change during the proceedings. Intentional homicide, preterintentional homicide, and anomalous complicity are not interchangeable labels: they require different assessments on intent, predictability, and individual contribution. Even an initial charge does not replace the proof that must be formed and evaluated in adversarial proceedings.
Initial information must be read with precision. If you are involved in proceedings, it is useful to collect without altering the communications received, the available documents, and essential data about your position: which fact is contested, which conducts are attributed to you, what statements or elements are indicated, and in what phase the proceedings are. You can contact me to examine the meaning of the charge and the issues to be addressed.
Frequently Asked Questions
Can I be held liable for homicide if I did not strike the victim?
Yes, but not for mere presence. Complicity can also concern anyone who provides conscious material or moral help to the realization of the fact. However, a concrete contribution and the necessary subjective element must be proven. If you did not participate in the action, did not reinforce the criminal project, and did not perform a useful role in its execution, your position must be kept distinct from that of the material perpetrators.
If no one wanted to kill, is it always called preterintentional homicide?
No, not always. Preterintentional homicide requires acts directed at committing beatings or injuries and the causal link between such acts and death. In an affair with multiple people, Article 116 may instead be relevant if someone commits a more serious crime compared to what was intended by the others. The two figures depend on the initial conduct and the role of each participant.
Is a generic agreement to teach a lesson enough for complicity in intentional homicide?
A generic aggressive intent does not prove the intent to kill by itself. For complicity in intentional homicide, it must be demonstrated that death fell within the fact intended or accepted by the co-participant. Modalities of the action, instruments, words, behavior during the incident, and subsequent initiatives are elements to be evaluated together. The formula used among participants does not replace the ascertainment of facts.
What is the difference between Article 110 and Article 116 of the penal code?
Article 110 governs complicity in the realized crime. Article 116 instead concerns the co-participant who wanted a different or less serious crime compared to that committed by another participant, provided the event is a consequence of their conduct and concretely foreseeable. If the more serious fact was foreseen and the risk was accepted, the issue can become that of full complicity.
Does a minimal role exclude liability?
A minimal role does not automatically exclude complicity. If the contribution was concrete, conscious, and useful to the realization of the crime, liability can subsist even without a primary executive action. The minimal importance of the contribution can however assume relevance in the penalty pursuant to Article 114 of the penal code. First, the very existence of participation in the crime must be ascertained.
