The Böcek family from Hamburg fell ill in Istanbul on November 12 after sightseeing and eating street food. Initially treated and discharged for suspected food poisoning, they returned to hospital with worsening symptoms; the two children, then the mother and later the father, died.
Investigators shifted their focus to possible pesticide exposure after other hotel guests became ill. The hotel has been closed, forensic teams collected samples, and 11 people have been detained while laboratories carry out further tests.
