Why Arsonists Set Fires: A Momentary Sense of Release

Paris – July 13, 2026: In many regions of France, emergency response units have been under severe pressure for days. Smoke is drifting over fields and forests, roads are closed, and residents are being evacuated to safe places as a precaution. Alongside firefighting efforts, investigations are also underway into possible causes of the fires. Interior Minister Laurent Nuñez said over the weekend that 32 people suspected of having caused fires had been detained since the start of summer.

However, this figure alone does not reveal what may have motivated the individual suspects. There are major differences between negligence, deliberate arson arising from conflict, and pyromania as classified in psychiatry. Investigators must first secure the point of origin, examine possible technical causes, and then analyze testimony and evidence. Those detained are presumed innocent until a court reaches a decision.

Psychiatrist and forensic expert Laurent Layet describes pyromania as an impulse-control disorder. Those affected experience rising inner tension before the act, and setting a fire can bring a brief moment of relief. However, this feeling of release does not last. For this reason, the label “pyromaniac” cannot simply be applied to every deliberately caused fire.

According to experts, this condition is rare. People who set fires are not necessarily driven by fascination with flames or by such impulses. Arson cases may be motivated by anger, revenge, financial gain, an attempt to conceal another crime, or recklessness that can lead to dangerous and serious consequences. Criminal and psychiatric assessments therefore require close examination of each allegation.

For affected regions, this distinction is initially a secondary issue. What matters there is whether homes, farmland, and people can be protected. In the Pyrénées-Orientales department, a fire near Ille-sur-Têt has burned around 4,900 hectares of vegetation in recent days, according to the gendarmerie. Gendarmes assisted with evacuations, secured transport routes, and also took part in the investigation into the cause.

Extreme dryness and high temperatures increase the risk that a small spark will rapidly develop into a major fire. According to the government, nine out of ten forest and vegetation fires are caused by human activity, including not only deliberate acts but also unintentional ones. Prevention, regulations in high-risk areas, and prompt reports from residents therefore remain important parts of protective measures.

Laurent Layet’s explanation once again shows that a complex medical issue lies behind the term “pyromania.” It should neither be used as an excuse for destructive acts nor as a hasty label for suspects. While police and judicial authorities clarify individual cases, the immediate task for firefighters on the ground is to prevent further fires and evacuate people from danger zones.
