A confidential witness central to the FBI investigation into a Canadian former Olympic snowboarder accused of running a murderous cross-border drug trafficking conspiracy has been killed in an apparent assassination in Colombia, the Star has learned. The witness, who has not been identified in court documents, helped investigators dismantle a transnational drug trafficking operation allegedly led by ex-Olympian Ryan Wedding, and was expected to testify at trial in the United States. The development casts a cloud of uncertainty over the future of a high-profile case that has made headlines around the world. It also raises questions about what this will mean for a sprawling prosecution that’s unfolding both in U.S. court and in a series of proceedings being heard in downtown Toronto. https://www.thestar.com/news/gta/key-witness-in-fbi-cocaine-case-against-canadian-ex-olympian-ryan-wedding-is-assassinated-in/article_3d612e86-e30a-11ef-9b24-5f013b39461a.html
