Authorities are trying to find a convicted murderer from northwestern Minnesota who was released from prison last year and put on supervised release.

Joshua C. Hendrickson, 40, of Karlstad, has been wanted by the state Department of Corrections since Tuesday, according to the agency. It has not released details about why he has been labeled a fugitive.

Hendrickson pleaded guilty in 1999 in Kittson County District Court to second-degree murder and first-degree assault and was sentenced for fatally stabbing Christopher J. Nelson, 22, also of Karlstad, and injuring Benjamin Larson, who was 20 at the time, of nearby of Strandquist.

The stabbings occurred during a house party in Halma.

Hendrickson was released in November 2017 from St. Cloud prison after serving just under 18 years.
