If it’s true that he was into the sex trade, there is an outside possibility that Natalie could be alive.
Weren’t those initial, really early rumors all tied up with Peru? I found the idea that they all sold her into sexual slavery and were trying to hide the proceeds of the sale to be very convincing.
Survival might depend on compliance - perhaps Natalie fought back. Although, it is speculated that he may have used a fatal amount of drugs.
