What were seized in the helicopter by the troop together with Sonia?

Sonia has taken what will most likely be a one way trip to the US.
    The senior FARC commander is accused of running a drugs trafficking network that earned the guerrillas tens of millions of dollars. Sonia was captured in February last year, in a hell-borne raid by elite Colombian troops. Along with her were seized documents and a laptop computer that provided much of the information that would be used against her in court.
   Sonia’s extradition is a heavy blow to the FARC. Not only have their lost one of their top female commanders, but they fear that under pressure from US authorities and facing a sentence of more than 20 years in prison she may reveal crucial information about their finance system.
