A $4,500 donation has been given to the Washington County Sheriff’s Department specifically for water rescue equipment. The donation came from the Mark Knowler Memorial fund, which was established by his family after 24-year-old Mark Knowler died in an accident on March 24th, 2007. Sheriff Jerry Dunbar said in yesterday’s supervisors meeting that the Washington County Rescue helped with the accident in Keokuk County because Keokuk County did not have water rescue equipment.
