ST. PAUL, Minn. (AP) âÄî Friends and family of a missing University of St. Thomas student from Eveleth are waiting for news after a massive search turned up nothing. More than 500 St. Thomas students searched a St. Paul neighborhood near the Mississippi River on Monday for freshman Daniel Zamlen, but didn’t find him. University spokesman Jim Winterer says Tuesday that the university has renewed its request that amateur searchers stay off the bluffs above the river, which is running dangerously fast. The bluffs are slippery and crowds could obscure clues from professional searchers. A St. Paul police spokesman says a team of specially trained and equipped volunteers are searching the area Tuesday. Zamlen was last heard from early Sunday. He turns 19 on Wednesday.
