Jonathan Andic is currently in preventive detention following allegations that he murdered his father, Isak Andic, the 71-year-old founder of the fashion giant Mango. According to testimony provided by Estefanía Knuth to a magistrate in Martorell, Barcelona, the death occurred during a hike in the Serra de Montserrat in late 2024, where Jonathan allegedly pushed his father, causing a fatal 100-meter fall.
Why was the death of Isak Andic reclassified as homicide?
The case shifted from an accidental fall to a criminal investigation after Estefanía Knuth, Isak’s partner of six years, provided testimony to Spanish authorities. While Jonathan Andic initially claimed his father simply slipped on the trail, Knuth revealed a history of severe instability and conflict between the two men.
According to Knuth, the relationship between father and son was marked by “peaks and crises of confrontation.” These tensions centered primarily on the succession and leadership of Mango. This testimony prompted investigators to examine new evidence, leading a judge to find sufficient grounds for Jonathan’s preventive detention in May.
What were the motives behind the alleged crime?
Court testimony and reports indicate two primary financial and professional triggers. First, Isak Andic reportedly planned to remove Jonathan from the management of Mango effective January 1, 2025. Sources close to the company’s executive team claim this exit had been in preparation for a full year prior to the tragedy.
Second, Estefanía Knuth testified that Isak intended to draft a new will. According to Knuth, the founder planned to significantly reduce the inheritance percentages for his three children—Jonathan, Judith, and Sarah—and instead use hundreds of millions of euros to establish a charitable foundation.
The history of the father-son conflict
The friction between the two men dates back to at least 2014. In that year, Isak voluntarily stepped away to sail the world on his luxury yacht, Nirvana Formentera, leaving Jonathan to manage the business. However, the trip ended after one year because the company faced a severe treasury crisis and plummeting profits.
According to the case details, Jonathan felt “wounded in his pride” after being removed by his father and the board of directors.
How did the family attempt to resolve these disputes?
Estefanía Knuth testified that she suggested the father and son undergo psychological therapy to overcome their personal frictions. She recommended the services of Julia L., a German-born Ecuadorian therapist specializing in psychoanalysis who works with high-net-worth families in Barcelona.
Knuth stated that the therapy took place and initially appeared to yield “relatively good results,” improving the family dynamic. Despite this, the private conversations between Isak and Knuth revealed that the founder still intended to sideline his son from the company.
What is the distribution of the Andic fortune?
The total estate is estimated at over five billion euros. While the majority is destined for the children and close collaborators, Estefanía Knuth is slated to receive 70 million euros and several real estate properties.
| Beneficiary | Reported Allocation/Status |
|---|---|
| Jonathan, Judith, & Sarah | Facing potential reduction via new will |
| Estefanía Knuth | €70 million + properties |
| Proposed Foundation | Hundreds of millions (Planned) |
