Yoland Simmons, Keland Simmons, Rachel Lehmann, and Elmer J. Laporte killed in collision involving semi trucks on Interstate 12 in Covington, Louisiana
The crash, which involved two 18-wheelers and multiple vehicles, occurred Saturday afternoon on I-12 at Highway 21.
Around 4 p.m. Saturday, the 18-wheeler approached congestion on I-12 east at Louisiana south of Covington. For unknown reasons, the truck failed to stop and started a chain reaction crash with nine other vehicles.
In the days following the crash, I-12 safety became a focus in St. Tammany, with some residents and elected officials renewing efforts to start a much-anticipated expansion of the highway through the Covington area - including the very spot where the crash occurred.
