Swiss officials have officially closed an investigation into the death of Liam Byrne, a 24-year-old British wingsuit flyer who died in June of last year. Mr. Byrne, a recognized champion in the sport, sustained fatal injuries while attempting a jump from the Gitschen mountain in the Swiss Alps.

Following the incident, local authorities launched an inquiry to determine if criminal negligence or other factors played a role in the accident. The investigation was categorized as a 'potential crime' probe, a standard procedural step in Switzerland when a death occurs under specific circumstances during extreme sports activities. After reviewing the evidence, prosecutors have decided to drop the case, effectively ruling the death an accident. No further legal action will be taken against any parties involved in the organization or facilitation of the jump.
