The Pottawattamie County Sheriff’s Office reports a Cass County woman was arrested Saturday afternoon following a reported assault in Walnut. Officials say 28-year old Jessica Lynn Gross, of Atlantic, was charged with Assault Causing Injury, following the incident that took place at Haystacks Diner on Antique City Drive, in Walnut.

Deputies were dispatched at the restaurant at around 2:45-p.m. following a report of an assault in progress. Brandi Smith, of Walnut, reported to the deputy her sister, Jessica Gross, had just assaulted their other sister, 19-year old Mary Smith, of Casey, and then left the scene. Mary Smith was transported to the Cass County Memorial Hospital in Atlantic, for treatment of a cut to her forehead.

Atlantic Police, having been notified Jessica Gross was on her way back to Atlantic, located the woman on the western edge of the City, during a traffic stop. The Pott. County Deputy arrived not long afterward, and took Gross into custody on the assault charge.
