The Murder of Marcel von Allmen

Marcel von Allmen was 19 when he disappeared from the Interlaken area in late January 2001. He had been associated with a self-styled right-wing extremist fraternity known as the Order of Aryan Knights. Investigators concluded that fellow members killed him after accusing him of violating the group's secrecy rules.

Marcel von Allmen

Von Allmen lived in Unterseen in the Bernese Oberland. Contemporary reporting described him as having been involved with the extremist circle but also as having tried to distance himself from it. The criminal case centered on what the defendants themselves said was punishment for breaking the group's code of silence.

The killing and discovery

Detailed Swiss reporting places the killing on the night of January 27, 2001, near the Weissenau ruins outside Interlaken. Von Allmen was attacked with a metal bar. His body was weighted down and disposed of in Lake Thun, where it was found on February 23.

This file does not reproduce unnecessary injury detail. What matters to the legal record is that the courts treated the killing as deliberate, planned murder rather than a spontaneous assault.

Arrests and admissions

Police arrested four young men shortly after the body was recovered. All were linked to the Order of Aryan Knights. Contemporary reports said the men admitted involvement and told investigators that von Allmen had been punished for violating the group's secrecy rules.

The group was described in court reporting as a small extremist fraternity formed around 1999. Police also investigated preparations for other planned killings, but those allegations are kept separate from the completed murder of von Allmen.

Juvenile and adult proceedings

One defendant was 17 at the time of the crime and was tried separately in juvenile court, where he was convicted of murder in December 2001.

The three adult defendants were tried in 2004. The Interlaken-Oberhasli district court convicted all three of murder and related offenses. The principal offender received life imprisonment. The two adult accomplices each received 16-year prison terms.

Appeals

In August 2005, the Bern cantonal high court upheld the principal offender's life sentence. The appellate court found the gravity of the crime justified the maximum penalty.

The case then reached Switzerland's Federal Supreme Court. In June 2006, the court rejected the principal offender's complaint, including his challenge to the psychiatric expert, leaving the life sentence in place.

What the case established

The convictions establish that von Allmen was intentionally killed by members of the extremist circle to which he had been connected. Reporting also documented broader extremist ideology and alleged plans for additional violence, but this page does not use those allegations to create separate crimes or inflate the case count.
