PORT HURON, Mich. (AP) - The U.S. Coast Guard says authorities are searching for 19-year-old man who disappeared while participating in the St. Clair River during the annual Float Down.

Lt. Kelly Ridle tells The Associated Press that Brady Morton was with a group of people who were taking part Sunday’s event. She says she didn’t know his hometown.

Ridle of the Coast Guard Ninth District in Cleveland says that the people who were with Morton couldn’t say when they last saw him.

The lieutenant says a Coast Guard helicopter and boats from several agencies were involved in the search.

People in tubes and rafts entered the U.S.-Canada border river Sunday at Lighthouse Beach in Port Huron, about 55 miles northeast of Detroit. They were exiting at Chrysler Beach in Marysville.
