Campus police still pursue leads in the disappearance of Andrew Sadek
Thursday marks three weeks since North Dakota State College of Science student Andrew Sadek disappeared and still, no clues to his whereabouts.
Sadek was last seen on the Wahpeton campus May first.
Law enforcement agencies spent a week searching ditches, fields and the Wild Rice River, but found nothing.
A week after he disappeared, authorities issued warrants for Sadek's arrest on drug charges.
Campus police say they are still pursing leads in the case, but the number of tips has diminished.
