Therapist, widow and hikers testify in probe into Mango founder's death as judge examines third-party influence
Five witnesses gave testimony on Tuesday in Martorell in the investigation into the 2024 death of Mango founder Isak Andic, as the judge explores possible influence from the family therapist.
Hikers describe Jonathan's state
Two hikers who encountered Jonathan Andic minutes after his father fell from a cliff in Montserrat on 14 December 2024 testified publicly for the first time. They told the court they found Jonathan "affected, in shock and blocked", already speaking to emergency services on the phone. One of the hikers spoke to the 112 operator to provide the exact coordinates of the fall site. He then walked Jonathan to a nearby parking area, a roughly ten-minute trek, and waited with him until firefighters arrived.
He was affected, in shock and blocked.
The hikers recalled that Jonathan told them he had been walking ahead and heard stones falling behind him. They confirmed the path was generally safe, but the spot where Isak Andic fell was the only point where slipping meant a fatal drop.
Widow's scepticism
Estefanía Knuth, Isak Andic's partner and a former professional golfer, was the first person Jonathan called after the fall, before contacting emergency services. The content of that call has not been made public. Knuth testified for about two hours and fifteen minutes. She is the only family member who does not believe Jonathan is innocent, and she has consistently spoken about the strained relationship between father and son. Her phone is to be forensically copied, as are those of the hikers, to verify locations, routes and emergency calls.
Therapist under scrutiny
Julia Lundervat, the family therapist, testified for nearly three hours without invoking professional secrecy, a change from her earlier refusal to answer police questions. She is not registered with any professional college in Spain; it is unclear whether she holds a formal qualification. The judge, Raquel Nieto, is examining whether Lundervat influenced Jonathan. In a previous order, the judge cited "the possible influence of third persons on the events".
The therapist had threatened to abandon the therapy if Isak Andic did not advance money to Jonathan.
The prosecutor, Teresa Yoldi, pressed Lundervat on her insistence that Isak give Jonathan 40 million euros as an early inheritance to ease the conflict. Lundervat sought to explain the family therapy sessions and contextualise messages in which Jonathan expressed hostility toward his father. After her testimony, she left the courthouse escorted by Mossos d'Esquadra and did not speak to the media.
Sister also testifies
Lundervat's sister, Rita L., who assisted in some of the Andic family therapy sessions, gave a shorter statement lasting about 45 to 50 minutes. Both sisters arrived separately and left without commenting. The prosecutor did not request a change in Julia Lundervat's procedural status; she remains a witness, not a suspect.
- Two hikers testify, describing Jonathan as affected, in shock and blocked
- Therapist Julia Lundervat begins testimony, lasts nearly three hours
- Lundervat concludes; her sister Rita L. testifies for about 50 minutes
- Widow Estefanía Knuth begins testimony, testifies for about two hours and 15 minutes
Broader investigation
Tuesday's hearings follow Jonathan Andic's release on bail a month and a half ago after he was formally accused of homicide. The judge has ordered the cloning of mobile phones belonging to Knuth and the hikers to verify locations and call logs. Knuth recently received 27 million euros from Isak Andic's estate under a settlement with his children, ending a legacy dispute.
