DETROIT — Drug and border officials from the United States and Canada said Tuesday they have shut down a drug route that used row boats to move large volumes of cocaine and marijuana into Michigan from St. Joseph Island, Ontario, south of Sault Ste. Marie.
Traffickers were using the boats at night to move drugs across the St. Mary's River into the Upper Peninsula south of Sault Ste. Marie, officials said.
