He and other officers had responded to the man’s home, in Minden, after receiving reports the man had shot at his wife during an argument. He parked his patrol car and went to the porch of the home. His patrol car then rolled into the porch, knocking it down. The porch roof fell onto Chief Deputy Otto causing fatal injuries.

Chief Deputy Otto had served with the Pottawattamie County Sheriff’s Office for six years and had previously served with the Council Bluffs Police Department for eight years. He served as the president of the Iowa Sheriff’s and Deputies Association. He was survived by his wife and two daughters.
