Members of a forensic team work at the wreckage of a helicopter where Mexico’s Interior Minister Francisco Blake and seven others were killed on a hillside south of Mexico City November 11, 2011. President Felipe Calderon said conditions were cloudy when the helicopter came down so that an accident looked probable. But in a televised address, he said no explanations for the crash could be ruled out as he paid tribute to Blake, calling him „a great Mexican.” REUTERS/Stringer (MEXICO – Tags: POLITICS OBITUARY)
