A predawn-commute crash on U.S. Highway 12 outside Walla Walla, Washington, left one driver dead and two teenage passengers critically injured on Tuesday, September 15, 2026. Authorities say a westbound sedan crossed into oncoming traffic near Interchange Road and collided head-on with an eastbound semi-truck. The impact closed Highway 12 in both directions at milepost 342 for several hours during the morning commute. The truck’s driver was not injured. Washington State Patrol troopers, including a collision reconstruction specialist, are still working to determine why the sedan left its lane.
According to AppleValleyNewsNow.com, the sedan’s driver was identified as 27-year-old Daniel Boggs of Dayton, who was pronounced dead at the scene. The outlet reported that his two passengers, both under 18, were airlifted to a hospital in the Spokane area with serious injuries. NBC Right Now additionally reported that Washington State Patrol Trooper Daniel Mosqueda said evidence indicated the sedan crossed the center line before striking the commercial vehicle, which was towing a trailer and pup trailer. Highway 12 reopened by early afternoon after crews cleared the scene and completed their initial investigation.
