Brown bleeding when they were summoned to a downtown address shortly before 9 p.m. Friday (12/21).  Police say Brown was taken to a Knoxville hospital, where he was pronounced dead. He was later taken to the Iowa State Medical Examiner’s Office for an autopsy. Autopsy results are pending. Law enforcement says a person of interest has been interviewed, but no arrest has been made and no charges have been filed. The case remains under investigation.
