5/10/17 – A 19-year-old man has been charged with making threats that closed one northwest Wisconsin school district and put another one on lockdown Tuesday. Burnett County prosecutors filed charges against Jacob Wicklund of rural Siren that triggered an arrest warrant — and officials say he was booked into jail Tuesday morning on a felony count of making terrorist threats and misdemeanor disorderly conduct. Grantsburg schools were closed Tuesday upon word on the threats, and the nearby Siren district had its schools on a 90-minute lockdown with police monitoring after that. Officials say Wicklund posted threats on a private Facebook page, and his stepfather read the messages later and called police — and he reportedly told officers that Wicklund is bipolar, with drug and alcohol problems. There’s no word on when Wicklund will make his first court appearance.
