At the time, Insp. Gary Godziuk called it a "rare event" in Edmonton, and said there was no connection to domestic or international terrorism.

Police also found two stolen skid steers, which are often used for construction or heavy lifting, and a stolen flat deck trailer.

In a related search at 39th Avenue and 76th Street the same day, police found methamphetamine, hashish, heroin, 50 grams of marijuana, hundreds of synthetic marijuana pills, drug scales, baggies and just over $3,000 in cash.
