The 71-year-old was found dead after falling over 100 meters down a cliff in the Montserrat mountain range near Barcelona.
The death was quickly deemed an accident, but on Friday, the Spanish police report that Andic's death is now being investigated as a suspected murder. The news comes after the Spanish newspaper El País on Thursday reported that the son, Jonathan Andic, the only one who was with the Mango founder the day he died, is now being investigated in the case, according to sources.
According to the sources, the son has given contradictory testimonies that have raised the investigators' suspicions. The newspaper La Vanguardia's sources report that the police in September changed Jonathan Andic's status from "witness" to "suspect" in the investigation. The son's partner is said to have described the relationship between the father and son as "strained" in an interrogation.
Isak Andic was, before his death, Catalonia's richest man and one of Spain's richest people.
