MINNEAPOLIS (AP) — The man charged in the political assassinations of the top Democrat in the Minnesota House and her husband, as well as the attempted murders of a state senator and his wife, is due to appear in federal court Thursday to change his not-guilty plea, after federal prosecutors said they would not seek the death penalty against him.

The U.S. attorney’s office in Minneapolis notified the court Wednesday that the Justice Department would not seek the death penalty against Vance Boelter in accordance with a proposed plea agreement. Boelter’s attorneys did not immediately respond to an email seeking comment. The court filing did not detail the terms of the plea agreement.
