Many detainees of the ICTY signed, this time, a true obituary, to Slobodan Milosevic, the people who signed it belong to different warring factions in the Balkan conflict. One of them is the recently arrested Croatian general Ante Gotovina (He dennies having signed it arguing that he only expressed his condoleances to Milosevic's family "as a good Catholic". The obituary says, “Farewell to the Hague fellow-fighter Slobodan Milosevic”.
