SIOUX CITY, Iowa (AP) — A man accused of helping another man flee Sioux City after shooting a police officer has pleaded guilty to a federal conspiracy charge. The Sioux City Journal reports that 25-year-old Esteban Hernandez pleaded guilty Friday in Sioux City’s U.S. District Court. Hernandez faces more than a year in prison when he’s sentenced.

Hernandez was arrested last month in Texas after being indicted in November. Hernandez was accused of driving Jamal Dean to Winnebago, Nebraska, a day after Dean shot Sioux City police Officer Kevin McCormick during a traffic stop in 2013. Hernandez later tried to take Dean to Mexico.

Dean was sentenced to 25 years in prison after pleading guilty to attempted murder.
