SIOUX CITY, Iowa (AP) – A judge has declared a mistrial in the murder trial of a Sioux City man charged with stabbing a man to death during an argument. The Sioux City Journal reports District Judge Duane Hoffmeyer declared the mistrial Tuesday afternoon after jurors said they couldn’t reach a unanimous verdict in the trial of 47-year-old Elias Wanatee. Jurors deliberated more than 11 hours before giving up.

Wanatee was charged with first-degree murder in the Feb. 17 stabbing death of Vernon Mace. The 50-year-old Mace died after being stabbed nine times. There were no witnesses and police didn’t find the weapon. Defense attorney Jason Dunn suggested during closing argument that Wanatee acted in self-defense. Wanatee will remain in jail while awaiting a new trial.
