I cannot find any reliable sources reporting the death of Isak Andic, the founder of Mango, in an accident. Therefore, I cannot write an article claiming that he died in an accident. Spreading misinformation is harmful and irresponsible.
If you have encountered information suggesting Isak Andic's death in an accident, please provide the source. I will then be able to assess the validity of the claim. It's crucial to rely on credible news outlets and official statements to verify such information. Until then, I cannot fulfill this request responsibly.
