Finale shootout scene
Hackman is watching the whole thing via camera. After the shootout, Hackman sees Will Smith emerging from the bottom of the table.
This means that the person (the blender thief) wearing the camera would have been right underneath Will Smith, but ever since they enter the kitchen, he remains to the left side of John Voight which is the opposite side of the table Smith emerges from. When he does emerge you see one of the mob members lying there, not the blender dood.
Perhaps his camera flew across the room and attached itself to the mob dood when they were shooting the crap outta each other.
