It was an odd case. Smuggling large amounts of bulky cannabis in suitcases on flights is rare. Border officers at Heathrow are used to pulling people for carrying cocaine, not huge amounts of weed.
But people kept on being arrested after coming across the Atlantic with suitcases full of weed: a 23-year-old male model from New York, a 26-year-old photographer from California and a 29-year old former strip bar waitress from Texas.
Within a week of Malone being caught in January this year, another 10 US citizens, all travelling from LA with similarly large amounts of weed packed into suitcases, were picked up at Heathrow.
