A 44-year-old former drug addict and alcoholic who now works as a minister was the sole person responsible for the brief hijacking Wednesday of a commercial jetliner, a Mexican official said. The suspect, Josmar Flores Pereira, told authorities he hijacked the jet on Wednesday because the date — September 9, 2009, or 9/9/9 and 666 reversed — held some significance for him, said Genaro Garcia Luna, the secretary for public safety.
