ST. CHARLES, Ill. (AP) — An Illinois State Police trooper has pleaded guilty to driving drunk while on the job.

The Kane County state’s attorney’s office says 34-year-old Paul A. Zurn responded to a minor crash in August when other officers saw him walking unsteadily. They also spotted a bottle of alcohol in his squad car.

A Tuesday statement from prosecutors says Zurn refused to take a blood-alcohol test. As a result, his driver’s license was suspended for a year.

Zurn agreed Monday to a sentence of one year of court supervision in exchange for his guilty plea to a DUI. That’s a Class A misdemeanor.

Zurn must also pay more than $2,000 in costs and fines, as well as attend a victim-impact meeting.

A phone message for Zurn’s attorney wasn’t immediately returned.
