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. The judge must approve the insanity plea before Holmes can change his plea.
Holmes could be executed if he's convicted of more than 160 counts of murder and attempted murder.
Holmes' attorneys have said in court hearings and written in court documents that Holmes is mentally ill. He was being seen by a psychiatrist before the attack on a midnight screening of the latest Batman movie that killed 12 people and injured 70.
