I heard earlier today that Joran is fluent in Spanish. Who knows what language he used on his laptop, could have been in English.
I do not know anything about the passport situation. But apparently he was already being 'hunted' halfheartedly by US for extortion attempt on someone from Alabama. They had to goods on him but let him leave and off to Peru he went.
The extortion was to tell what happened to Natalie and where her remains were put. So given he was dealing with people/person in Alabama he could have left open something in English about $$$$$ he was extorting to go gamble in Peru. We won't know until they publish what is found on his laptop.
In exchange for money, he was going to tell the family where to find Natalie's body. This guy needs to be put away for life.
