Authorities resumed their search Monday for a St. Cloud State University student who hasn’t been seen since early Saturday, when he turned up on video surveillance walking downtown, authorities said.

Jesse A. Dady, 21, was the subject of an extensive search by St. Cloud fire and police personnel Sunday as they navigated the Mississippi River and scanned the shoreline. Search personnel were preparing to return the river later Monday afternoon.

So far, police are saying the disappearance of the Princeton, Minn., native is not the work of foul play.

The video footage showed the college junior walking alone at about 1:30 a.m. northbound on 5th Avenue N. and crossing 1st Street N. just east of 5th and less than two blocks from the river. Police searched that part of the city and came away with nothing.

Also Monday, police say they are trying to identify and speak to the driver of a light-colored sedan that was near where Dady was last seen and about the same time. Video surveillance picked up the car driving around the back of the Empire Apartments and then leave minutes later. Police have released to the news media a still image of the car from the video.

Dady is described as white, about 6 feet tall and 150 pounds, with hazel eyes and blond hair. He was last seen wearing a blaze orange hat, gray jacket and bluejeans.

Anyone with information about Dady’s whereabouts is urged to contact police at 1-320-251-1200 or Tri-County Crime Stoppers at 1-320-255-1301, 1-800-255-1301, www.tricountycrimestoppers.org or by text. Enter 274637 (“Crimes”) start the text with TRITIP. Then enter a space before the information.
