The search for a missing kayaker on the Minnesota River near Courtland continued on Tuesday, but there’s still no sign of 51-year-old Stephen Fritze of Watertown, South Dakota. Fritze has been missing since his kayak overturned near a bend in the river Saturday night. Day 4 of the search on Tuesday saw rescue personnel bring in K9 units from Fargo and Golden Valley to assist in the search. They reportedly spent around 2 hours on the water, and the dogs did apparently find positive signs where the teams have been searching, indicating that they have been looking in the right place. The search continues today (WED).
