The accused, Sheldon Aitken, was charged with importing cocaine.
His mother, Shelley Aitken, initially implicated him but recanted at trial, claiming fear.
The court found the accused's testimony incredible and accepted the mother's prior statements and the husband's corroborating evidence.
The court concluded that the accused orchestrated the trip to Costa Rica for drug importation and knowingly placed cocaine in his mother's luggage.
The accused was found guilty beyond a reasonable doubt.
