WAHPETON, ND. (KFGO AM) -- The parents of a missing North Dakota State College of Science student say they want their son to return home.
20-year-old Andrew Sadek hasn't been seen since last Thursday, when he left a residence hall on the NDSCS campus.
Andrew's mother, Tammy Sadek, says so far, no clues have turned up to indicate what might have happened to her son.
Richland County Sheriff Larry Leshovsky has expanded the search area for Sadek.
Searchers are using atv's, a boat and divers to check a ten mile long area along the Bois de Sioux to the Tyler area.
Leshovsky says the request to search south of Wahpeton came at the request of the college.
