The North Dakota Supreme Court has tossed out the sentence of a man convicted in the Savannah LaFontaine Greywind murder case.

The Bismarck Tribune reports during the trial a judge had granted prosecutors' request to label William Hoehn a "dangerous offender," enhancing his maximum sentence.

In their Thursday ruling, the Court said the judge should not have handed down that designation, and the court must revise the sentence.

William Hoehn was convicted for his role in the case involving Savannah Greywind, a Native American woman living in Fargo.

Prosecutors said he conspired to kidnap the baby that his girlfriend had cut from Ms. Greywind's body. The defendant's girlfriend Brooke Crews, had previously admitted to cutting the victim open and removing the child.

The trial created a sensation and sparked a movement among political activists to lobby for new laws protecting Native American women.

A new sentence for Mr. Hoehn is pending.
