prove that holmes was insane at the time? >> remember, here in colorado it is the prosecution's burden to prove holmes was sane at the time of the shoots but the defense did just wrap up its side of the case last week and they did present two mental health experts whom they had asked to do mental evaluations of holmes and who told the jurors they believed he was insane at the time of the crime. one of those experts was a specialist in schizophrenia and she was last to take the stand for the defense and talked about how holmes was suffering from a delusional system, she said, that really made him believe he had to carry out a mission to kill to increase his own self-worth. she said he was detached from reality. he didn't have control of his actions and was unable to understand morally what was right from wrong. the defense put together a string of videos showing holmes in jail after he has been arrested in which he acted in a very bizarre manner.
