On 28 December 2007, Stevan Zečević, Zorica Lazić and Elmir Kuduzović, who had all been evicted earlier in the season, were killed in a car crash. The crash occurred when their Citroën C4, driven by Kuduzović, ran off the road near the town of Ušće, Serbia. The car reportedly skidded off the road due to excessive speed on a turn, flipped onto its roof and landed in the Vukodraž River. The crash happened on Obrenovac-Šabac road, which was icy at the time. A fourth person in the car, Vladimir Sarić, who was not a member of this season's cast, was injured in the crash.
