Andrew Sadek (born November 22, 1993–died approx. May 1, 2014), was a student at the North Dakota State College of Science (NDSCS) in Wahpeton, North Dakota, United States. Following a 2013 arrest for felony charges of selling marijuana that legally could have resulted in a long prison sentence, Sadek agreed to work as a confidential informant (CI) for the South East Multi-County Agency Narcotics Task Force (SEMCA) in exchange for having the charges dropped. Under police supervision, he bought more marijuana from other dealers around the NDSCS campus.
