FARGO, N.D. (AP) — A judge overstepped by giving a life prison sentence to a man whose girlfriend cut the baby from the womb of an unsuspecting neighbor, the North Dakota Supreme Court ruled Thursday, ordering that the man be resentenced.

William Hoehn of Fargo pleaded guilty to conspiracy to commit kidnapping in the August 2017 attack on Savanna Greywind, who died of her injuries but whose baby survived. He entered the plea before a jury acquitted him of conspiracy to commit murder.

Hoehn’s girlfriend, Brooke Crews, admitted that she sliced Greywind’s baby from her womb. She pleaded guilty and was sentenced to life in prison without the possibility of parole.

Hoehn had faced a maximum of 20 years behind bars for the kidnapping charge and an additional one year for lying to police, but Judge Tom Olson granted prosecutors’ request to label Hoehn a dangerous offender, enhancing his maximum sentence to life with the possibility of parole.

The state Supreme Court, though, ruled that Hoehn shouldn’t have received that designation and ordered that he be resentenced.

Kiara Kraus-Parr, who argued the appeal for Hoehn, called it a “pretty clear-cut case” and said she had been “cautiously optimistic” that her client would prevail.

“I think the state overreached in what they charged, as far the special dangerous offender,” she told The Associated Press

Cass County prosecutor Leah Viste said it was a difficult case to try because there was no dangerous offender case law in North Dakota.

“The Supreme Court has spoken now and given us more guidance,” Viste said. “It’s disappointing for us, certainly, but we accept their ruling. There is nothing glaring that stands out for us that would call for a rehearing.”

The justices said that for Hoehn to qualify as a dangerous offender, his 2012 conviction for abuse or neglect of a child would have to be similar to the conspiracy to commit kidnapping charge. A comparison of the elements of the crime did not support the finding that the two offenses were comparable, the court found.

A new sentencing date should be set in two weeks.

Gloria Allred, attorney for the Greywind family, told KFGO radio that the family is shocked by the ruling and says Greywind’s mother and father are worried about the safety of her granddaughter.
