Marianne von Gierke: What Is Publicly Reported

BioBioChile reported on October 15, 2026, that Chilean athlete Marianne von Gierke, 40, died during the early hours of October 14 in Punta Arenas. The report said her cause of death had not been officially confirmed, so no cause should be presented as established.

An official IFBB Pro results page lists Von Gierke representing Chile and winning Women’s Physique Open at the 2026 Rising Phoenix in Phoenix, Arizona, on August 22, 2026. That result is a documented recent achievement, but it does not establish a complete biography or explain the reported death.
