DENVER -- New court documents were released in the murder trial of James Holmes Friday, alleging the suspected gunman in the Aurora theater tragedy told a classmate he wanted to kill people in March -- four months before the shooting.
One of those court documents was a motion from prosecutors seeking access to Holmes' records from the University of Colorado-Denver's graduate program of neuroscience.
According to the motion, Holmes "had conversations with a classmate about wanting to kill people in March, 2012, and that he would do so when his life was over."
Arguments presented at a court hearing Thursday began to reveal a possible motive behind the attack prosecutors say Holmes committed at the premiere of "The Dark Knight Rises" in July, which left 12 dead and 58 injured.
Prosecuting attorney Karen Pearson said that Holmes began "buying an enormous amount of ammunition, body armor and explosives" at the same time he was on the verge of flunking out of a graduate neuroscience program at the CU's Anschutz Medical Campus.
Prosecutors say Holmes left that graduate program in June after failing his final examinations at the end of the semester and making threats to a professor.
Holmes' defense attorneys have said he is mentally ill and are arguing for his university records to remain sealed.
