Police and the Department of Fisheries and Oceans are continuing the search for the body of a pregnant teacher who died after her car plunged into the North Thompson River, police announced Wednesday.

Clearwater Mounties said search and rescue crews have exhausted their efforts, but divers, air services and DFO boats continue to canvas the river in hopes of locating the body of Courtney Buck.

The body of Courtney’s husband, Skye Buck, was recovered on Tuesday when crews salvaged their vehicle, which was submerged 12 feet in the river.

The couple, both 30-year-old school teachers, died after their car lost control on an ice and snow-packed patch of Highway 5 then crashed down a 30-meter embankment into the river.

Police said an extensive underwater search around the vehicle and rivers edge was unsuccessful in locating Courtney.

The dive team is now using sonar equipment in areas where it is too dangerous to descend because of fast currents and the unpredictability of the river.
