He said he will reveal the location of Natalie’s body if he is brought back to Aruba.
I just don’t see Peru giving him this opportunity.
He also said he lies >60% of the time. Is this also a lie?
They won't. Senor Flores is a man of influence in Peru, and Peru doesn't really care about what happened in Aruba some years ago. They care about what happened in Lima recently. They've secured a confession from the creep and aren't going to jeopardize their case by injecting anything from the past into it.
Van der Snoot is going down, into a Peruvian prison, and that's that. Senor Flores may, or may not, arrange to have Van der Snoot killed, or some con may do the job unasked, in order to curry some favor with upper-class Lima society...
