DENVER (AP) - Lawyers for the man accused of killing 12 people and injuring 70 in a Colorado movie theater say he wants to change his plea to not guilty by reason of insanity.
    
Attorneys for James Holmes said in a court filing Tuesday they plan to formally ask for the change of plea at a May 13 hearing.
    
A judge in the case previously entered a standard not guilty plea for Holmes.
