James Holmes told his psychiatrist that he wanted to kill people more than a month before his murderous rampage at an Aurora, Colorado movie theater in 2012. The Associated Press reported the news Wednesday from documents that were not released during Holmes’ trial. The head of his neuroscience graduate program told campus police that Holmes said he kept having homicidal thoughts to make up for his failure in science. University of Colorado cops “did little other than check to see whether Holmes had a criminal record and deactivate his campus access cards,” the AP writes. The psychiatrist did not detain Holmes because his descriptions were abstract and she feared doing so would “inflame him.” Last month, Holmes was found guilty of 12 counts of murder and will serve life in prison.
