Six Dead in Kerzers Bus Fire; Police Release New Details
Fribourg cantonal police have confirmed that six people died after a fire was intentionally set on a PostBus in Kerzers. New details indicate nine people were on board at the time, with three managing to escape with injuries.

Fribourg is reeling from a staggering tragedy that has claimed six lives in a matter of minutes. Police have confirmed that the devastating fire aboard a PostBus in Kerzers was not an accident, but a deliberate act of violence. Precisely nine people were on board the vehicle last Tuesday evening—a driver and eight passengers—when the inferno erupted shortly before 6:30 pm. While three individuals managed to escape the burning vehicle with injuries, six others, including the perpetrator, perished in the flames.
The swiftness of the destruction has shocked the nation. Authorities have now definitively stated that the fire was intentionally set, transforming a routine commute into a deadly trap. Among the survivors, a 56-year-old woman remains in a critical state, fighting for her life. This is not merely a transport accident; it is a crime scene of horrific proportions that has left the quiet community of Kerzers grappling with unprecedented grief.
The 'Disturbed' Recluse Behind the Blaze
The man responsible for this horrific act has been identified as Peter M., a 65-year-old Swiss national described by police as "disturbed." New details paint a picture of a man living on the fringes of society. For years, Peter M. lived as a recluse in a camping car near a farm in Canton Bern, a stay originally intended for a single winter that stretched into years of isolation. Reports indicate he was battling severe addiction problems and was known to police for violations of the Federal Narcotics Act.
His life was unraveling rapidly before the attack. He had recently been evicted from his campsite for failing to pay fees and was under administrative guardianship. Just days before the tragedy, he disappeared from a hospital in Bern, prompting a missing person alert. Despite police patrols searching his camper, he remained elusive until he boarded the bus in Kerzers. While social services noted no prior indication that he was a danger to others, his deteriorating health and desperate circumstances culminated in a final, fatal act.
Trapped in Motion: The Mechanics of the Tragedy
The terror inside the vehicle was compounded by the mechanics of the bus itself. Technical findings reveal a harrowing detail: the passengers were effectively trapped while the vehicle was in motion. Fribourg police emphasized that while the bus was equipped with two passenger doors that functioned correctly, safety mechanisms dictated that "opening them could take place only after the bus had come to a complete stop."
Because the fire was ignited while the bus was moving, the seconds before the driver could halt the vehicle likely determined the fate of those on board. Once the bus stopped, the doors opened, allowing three people to escape the inferno. Two brave bystanders also suffered injuries while attempting to rescue victims from the blaze. This delay between the ignition of the fire and the opening of the doors highlights the terrifying vulnerability of the passengers in those critical, final moments.
