A massive mudslide struck the Duffey Lake Road/Highway 99 corridor south of Lillooet, British Columbia, amid extreme rainfall and flooding. The collapse engulfed vehicles in its path and disrupted a major mountain route, trapping or sweeping away motorists.

Search and rescue teams recovered the body of a woman early in the incident, marking the first confirmed fatality linked to the slide. Over the next days, three additional bodies—belonging to men previously reported missing—were located, bringing the confirmed death toll to four.Authorities continue searching for another man who remains unaccounted for, though efforts have been constrained by hazardous conditions.

Officials say the landslide was one of many linked to a “Pineapple Express” weather system that brought unprecedented rainfall to southern B.C., triggering floods, washouts, and cascading infrastructure failures.  The road through the affected section remains closed, and crews are assessing whether portions can be safely cleared, or if alternate rescue or recovery methods will be required.  Families have been notified of recoveries, and the B.C. Coroners Service is leading investigations into the causes and circumstances surrounding the tragedy.
