A Cass County man walked into the Pottawattamie County Sheriff’s Office Tuesday morning, and turned himself-in. The Sheriff’s Office said 41-year old Jason Aaron Watson, of Atlantic, was wanted on a Pott. County warrant for Trespass. After the warrant was confirmed, Watson was taken into custody and transported to the Pott. County Jail. He posted a $300 cash bond that same day and was released.
