A Poweshiek County man is in custody after law enforcement says he started several fires and shot at them during a seven hour long standoff. The Poweshiek County Sheriff’s Office says it was called to a residence four miles southeast of Grinnell around 1:20 Wednesday afternoon (6/24). Family members said 49-year-old Dwaine Anthony Bauman was acting strangely with a gun. The Sheriff’s Office says when they contacted Bauman, he became aggressive. Bauman allegedly shot at deputies several times, but they didn’t shoot back. The Sheriff’s Office says in the meantime, Bauman set fire to a house, two vehicles, a barn and almost 100 bales of hay. No one was injured. Bauman was arrested for second degree arson and intimidation with a dangerous weapon.
