Law enforcement officers looking for a missing 13-year-old, James Yoblonski of Reedsburg, found signs of human activity while searching Baraboo Bluffs, making them feel optimistic. Over 90 police officers from across Wisconsin searched the Baraboo Bluffs in Sauk County on Thursday in a search that started on Monday. Sauk County officials found plastic sandwich bags, a boot print and walking stick 200 yards southwest from the abandoned campsite earlier in the week. Only trained law enforcement officers and first responders are allowed to search because officers and Yoblonski’s family believe he is in possession of a gun. Officers will continue the search Friday if Yoblonski is not located yet.
