A man went missing while kayaking the Minnesota River near New Ulm on Saturday evening, the Nicollet County Sheriff reported. The man, who was not identified, was with two others when their crafts overturned, according to the Sheriff Dave Lange.

Two of the kayakers made it to shore and called for help at 8:04 p.m. Emergency responders from Nicollet, Blue Earth and Brown counties, as well as the Courtland (Minn.) Fire Department, searched along the shore and by boat until sunset but found no trace of the man.

The search will continue at daybreak. The kayakers are from Watertown, S.D. The missing man was not wearing a life jacket, according to Lange.
