Another group called the Commission of Geneva was sent in Kosovo. This group was made up of Charles Graves, Verena Graf and Jean-Jacques Kirkyacharian. They didn't take blood analyses but during their trip they interviewed health personnel, children and their parents. They also took detailed notes of the symptoms. They wrote that some doctors had noticed a smell from the students which was similar to "vinegar". According to them, it was possible that the disease was caused from poisoning which might have been in the form of organic phosphates (nerve gas).Graf Verena/Kirkyachariean Jean-Jacques, Report of mission to Kosovo 1–5 July 1990.date 10 gusht 1990Mail fran Charles Graves date 11.10.2007
