A man charged with killing an Iowa State Patrol sergeant during an April standoff may have instigated the violent confrontation by goading an officer with whom he was angry to chase him. A police report shows that Michael Lang sped by Grundy Center reserve officer Cody Niehaus on April 9. Niehaus had cited Lang, a former Democratic candidate for Sheriff, for trespassing days earlier when Lang returned to a local bar where he had been banned. Niehaus says he hesitated on whether to pull him over but ultimately decided to try.
