Dozens of volunteers gathered at the Wisconsin Riverside Resort for a fifth day of searching on Wednesday, with volunteer organizations like Bruce’s Legacy, Wings of Hope, Minnesota-Wisconsin Search and Rescue joining local fire departments in the search. Several K-9 teams were out on the water, where volunteers said they were using sonar technology to probe the waves.
