A 50-year-old Shellsburg man charged with using a cattle prod on a 16-year-old girl pleaded guilty last week in Benton County Court.

Eric Kolsrud entered his written guilty plea to assault causing injury, a serious misdemeanor, and contributing to the delinquency of a minor, a simple misdemeanor, on Oct. 25. Sentencing is set 2 p.m. on Nov. 15.

According to a police report, Kolsrud used a “Hot Shot” shocking device on teenage girl following an argument last July. The shocking device is used to control livestock. Kolsrud also told a 15-year-old girl who lived in the same house to lie to officers if they asked her about the incident, authorities said.
