A devastating fire tore through a public bus in the quiet Swiss town of Kerzers, canton Fribourg, on March 11, 2025, claiming six lives and leaving five others injured in what authorities describe as a deliberate act of self-immolation by a troubled passenger. The blaze, which engulfed the vehicle in minutes, transformed an ordinary commute into a scene of unimaginable horror, with passengers trapped as flames spread rapidly and doors failed to open properly.

The incident began around 6:25 p.m. local time when a 65-year-old Swiss man from Bern, who had been reported missing by his family earlier that day, boarded the diesel postal bus in Düdingen. Carrying two bags, he sat quietly among the passengers before standing up, dousing himself with a flammable substance—believed to be petrol—and setting himself alight. The fire ignited instantly, racing through the interior and turning the bus into an inferno. Investigators, led by Fribourg canton’s public prosecutor Raphael Bourquin, confirmed the leading hypothesis based on witness statements, initial video analysis, and the sequence of events: the man acted alone, with no indication of terrorism or external involvement.

Among the victims was 26-year-old Lara Baumgartner, a charismatic Swiss radio presenter and DJ for Radio Energy. Her employer issued a heartfelt tribute, describing her as a “wonderful person” whose “laughter, her warmth, her subtle humour, and her intelligent, loving nature touched many people,” leaving “a void that is almost impossible to put into words.” Colleagues and listeners mourned the loss of a rising star known for her engaging on-air presence and genuine connection with audiences across the region.

Other fatalities included a 16-year-old boy, whose youth amplified the tragedy’s senselessness; the 63-year-old Portuguese bus driver, who had no chance to react; a 29-year-old man; and two women aged 25 and 29, all local Swiss residents. The five injured comprised two Swiss men (aged 34 and 61), two Swiss women (27 and 56, the latter still under hospital observation), and a 32-year-old man from Kosovo who suffered burns to his hands, nose, and legs while enduring severe trauma.

Survivor accounts painted a chilling picture. One passenger, Faton Morina, recounted receiving a frantic call to rush to the scene and described the suspect sitting nearby before the ignition. He noted the bus stopping abruptly as chaos erupted, with closed doors trapping people inside and forcing desperate escapes through the rear. Emergency services—firefighters, police, and ambulances—arrived swiftly but found the vehicle already a charred shell. Three of the injured required immediate hospital transfer, while two received on-site treatment.

Swiss authorities emphasized the suspect’s profile: a marginalized, psychologically disturbed individual known to medical services rather than criminal authorities, recently facing personal difficulties. Bourquin described him as “quite marginalised, someone potentially psychologically disturbed,” with prior knowledge in a medical context. The man is believed to have perished in the fire he started, ruling out charges but leaving investigators to piece together his motives through ongoing analysis of footage and background checks.

The tragedy prompted an outpouring of national grief. Swiss President expressed condolences on social media: “It distresses and saddens me that once again people in Switzerland have lost their lives in a severe fire. The circumstances are being investigated. To the relatives of the deceased from Kerzers, I extend my condolences. And I think of the injured and the rescue workers.” A specialist care team, dedicated hotline, and memorial site have been established to support grieving families, survivors, and first responders.

Questions linger about the bus doors’ functionality during the emergency, with police reviewing video to determine if mechanical issues or panic contributed to the high death toll. The rapid spread of flames in a confined diesel vehicle underscored vulnerabilities in public transport safety, though no prior warnings existed for this route.

Communities in Fribourg and beyond continue to reel from the loss. Radio Energy and local media paid tribute to Lara Baumgartner through special broadcasts and listener messages, celebrating her legacy while mourning what could have been. The 16-year-old victim’s family faces the unbearable task of burying a child on the threshold of adulthood, while the driver’s colleagues remember a dedicated professional who drove the same routes for years.

This incident, while isolated and not terror-related, highlights the devastating impact of untreated mental health struggles when they intersect with public spaces. Authorities stress that support systems exist, urging those in crisis to seek help. As investigations continue, the focus remains on honoring the victims and providing solace to those left behind in the wake of a fire that burned far too brightly, far too quickly.
