The search in the St. Clair River for a 19 year old Fenton man has been suspended. Authorities say the search and rescue efforts were put on hold as of 9 p.m. Monday after searching more than 157 square miles of river and waterways for Brady Morton, who was reported missing by friends during the Port Huron Float Down. A rescue boat and a helicopter searched the area throughout Sunday night and Monday, with crews using sonar to scan the water during much of yesterday. The St. Clair County Sheriff Marine Division reported that Morton was floating with a group of about 40 people when he left his raft to go swimming. His friends reported that he never came back. Morton is an experienced swimmer and president of the Water Ski Club at University of Michigan-Flint. He was wearing gray shorts and red sunglasses when he dove into the water. Anyone with information about Morton can call (313) 568-9560, or 911.
