Two Kitchener residents could face prison terms in the United States after pleading guilty to attempting to export drugs.

Karl and Sorina Morrison were arrested last October at a border crossing near Niagara Falls, N.Y.

They were accused of importing fentanyl products from China into the United States, and then attempting to mail them to Canada.

Authorities in the U.S. said that at least two packages mailed to Karl Morrison at a mailbox at a UPS store contained fentanyl.

When Morrison arrived at the store, he was under surveillance. Officers reported seeing him pick up the packages, open them up, and repack their contents into new envelopes – after which Sorina Morrison went into the store and mailed three parcels to Canada, claiming they contained cinnamon.

Sentencing will be take place in July.

Karl Morrison faces maximum penalties of 20 years in prison and a US$1-million fine for the offences he pleaded guilty to, while Sorina Morrison could be imprisoned for three years and fined US$250,000.
