The Eighth Circuit determined that Iowa's domestic abuse assault statute is divisible between assault with a dangerous weapon and assault with intent to inflict serious injury.  It further determined that assault is divided into three subsections: 1) assault intended to cause pain or injury; 2) assault intended to place another in fear of immediate physical contact which will be painful, injurious, insulting, or offensive; and 3) assault involving a firearm.  Assault with intent to inflict serious injury under the first definition of assault qualifies as a crime of violence.
