East-bound Highway 169 in LaPrarie was closed for up to three hours this morning. A semi truck with a trailer was pulling out from the L&M warehouse in LaPrarie when the trailer became detached. The driver of the semi, identified as Bernard Fredrick Schulte of Bigfork, stopped and got out of the truck. The truck driver was then struck by a Buick Century travelling eastbound. The Century driver, Michael David Yennie, administered aid and called 9-1-1. Schulte was taken to St. Luke’s in Duluth with life-threatening injuries.
