The large electrical transformers bound for Mexico were the perfect place to hide cocaine. It was a matter of chemistry to dilute the drug into an oil mixture that could be concealed as coolant, a job handled by a Mexican engineer working discretely in a suburban warehouse near Buenos Aires.
The transformers carrying 2 tons of liquefied cocaine from Bolivia were loaded onto a cargo vessel at a Buenos Aires port and shipped out to sea. But investigators had been watching the operation and when the shipment arrived, an Argentine judge was on hand to insist on a test that, to the astonishment of authorities at one of Mexico’s most secure ports, revealed the drug.
The traffickers, Judge Sandra Arroyo said, had used “an ingenious and logistically novel method for the deception.”
