that's the most normal thing of the planet:
It wasn't me, this is not mine, never in my life did i see this package.
does somebody know which car rental company this was?
i would guess(but don't know) they rented "from private".
then it is possible that the owners of that rental frequently deliver their packages that way form city to city within theDR, the police would not suspect much on a foreign rental car driver/tourist. they rent the cars to visitors to be driven from City A to City B an there they take out the package without anybody ever knowing anything bout the delivery.
in such case, thats the risk to rent from "someone", you never know what kinda guys those renters are.
anyways, They got caught with the brick, i don't see them to walk away from this any easy.
everybody claims to be innocent, to be set up, nobody really listens to such speeches anymore.
they each have a lawyer, they each have family in the US with money, they will do time and the families will pay nice bucks to get them some commodities on the inside, for a longer while.
there will be a lot of families fed with their money during these hard Pandemic times.
