 A former Rozo County deputy has pleaded guilty to stalking other detectives, according to court papers. 36-year-old Joshua Olson sent text messages to the wife of a Minnesota B.C.A. agent saying the family was being watched and threatened to murder the agent. Olson also allegedly hung posters containing a picture of another agent saying he was a sex offender. Gunshots were also heard outside of one of the agent's homes, leading to Olson's arrest. Now, the agents had previously investigated a case that cost Olson his job as deputy after he was convicted of shooting up a hunting cabin. Olson will be sentenced next month.
