Who Was Marianne von Gierke?
Marianne Belén Von Gierke Barassi came from Chile’s Magallanes region in the far south. She was a lawyer who graduated from the Universidad de Magallanes and later became one of the country’s leading female bodybuilders. She earned her IFBB Pro card in 2021 and competed in the Women’s Physique division.
Key career highlights include:
- Winning the Rising Phoenix Arizona Pro in August 2026
- Placing 13th at the 2026 Mr. Olympia (her second appearance after 16th in 2024)
- Earlier wins such as the Vancouver Island Pro in 2024
- Working as a fitness trainer and coach while balancing motherhood
She was also a devoted mother to an 11-year-old son. Just weeks after stepping on the Olympia stage in Las Vegas, she passed away in Punta Arenas after collapsing at home. Her husband rushed her to Clínica RedSalud Magallanes late on October 13. Medical teams attempted resuscitation, but she could not be saved. Preliminary reports point to sudden death, with an autopsy still pending as of mid-October 2026.
Marianne von Gierke’s Husband: Juan Cofré García
Juan Cofré García (also spelled Juan Cofre Garcia in some reports) was Marianne’s partner of approximately 10 years. Spanish-language sources often refer to him as her “esposo” (husband), while English coverage more frequently describes him as her longtime boyfriend or partner. Either way, he was the constant presence in her life.
He was the one who drove her to the hospital on the night she collapsed. In the days before her death, Marianne shared a heartfelt Instagram message thanking him for standing by her through every stage of a demanding competitive season. She described him as the person who lived the process with her—the good days, the doubts, the frustrations, and the goals. She wrote that he held “from the shadows a fundamental part of all they see on stage.”
García responded by expressing pride in her achievements and promising continued support. Their relationship stayed largely private, focused on family and her athletic ambitions rather than public spotlight.
