SIOUX CITY, Iowa (AP) — A judge has found an Iowa man mentally competent to stand trial in the slaying of a Nebraska man in Sioux City. Woodbury County District Court records say Judge Patrick Tott said in his ruling issued Tuesday that 31-year-old Daniel Levering may not be willing to assist in his defense but is competent to do so.

Levering has pleaded not guilty to a charge of first-degree murder. He’s accused of stabbing to death 36-year-old Vincent Walker on July 23, 2017. Walker lived in Winnebago, Nebraska. A trial starting date hasn’t been set.
