A Dysart man was killed in a Webster County accident late Thursday morning.

The Iowa State Patrol identified the victim as 68-year-old Ricky Mason. The crash also injured a semi driver, 58-year-old Kirk Gunderson of Hampton.

According to an accident report, Mason was driving on U.S. Highway 20 near Duncombe around noon, when he failed to slow down for a semi tractor-trailer that was turning onto a rural road in front of him. Mason's SUV slammed into the rear of the semi trailer.

Mason and Gunderson were both taken to a Fort Dodge hospital to be treated for undisclosed injuries. Officials said Mason died after arriving at the hospital.
