Andrew_SadekFARGO, N.D. (AP) – The family of a North Dakota college student who was a confidential informant for a drug task force has filed a wrongful death lawsuit.

The body of 20-year-old Andrew Sadek was found about two years ago in the Red River, which separates North Dakota from Minnesota, not far from where he attended college in Wahpeton. He died of a gunshot wound to the head.

John and Tammy Sadek filed a civil complaint Monday against Richland County Sheriff’s deputy Jason Weber and the county. The suit seeks unspecified damages.

The suit says the defendants, including Weber, who was part of the task force, failed to train Andrew Sadek to perform undercover operations or to “reasonably supervise” him.

A spokeswoman for the North Dakota attorney general’s office was not immediately available comment.
