A father and son both sustained serious injuries after a three vehicle crash this afternoon near Harrisburg.
The pair were riding a motorcycle east of Interstate 29 along County Highway 110. A pick-up truck cut in front of the motorcycle. There was a mini van behind the pickup that ended up clipping the motorcycle and running into the ditch.
The man driving the pickup along with the woman and her two kids inside the mini van were not hurt in the crash.
The case is currently under investigation by the South Dakota Highway Patrol.
