While preaching in a prison in Kazakhstan in 1992 a russian prisioner told me "There were 3 Americans in the last prison he was in" I quickly had him to write down the name and location of the prison before any guards saw us. When I returned to the states I turned the information over to the authorities, but as far as I know, nothing was done about it. The powers that be never contacted me, eventhough I had contacts in the country and made 10 follow up trips to the area. Rambo needs to look in Russia and Kazakhstan, not just Vietnam.
