The man accused of opening fire on an Aurora movie theater told a classmate he wanted to kill people four months before the shooting, newly released court records allege.
Prosecutors made the allegation in a motion released Friday seeking access to James Holmes' records from the University of Colorado Denver's neuroscience graduate program.
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," attorneys for the state wrote. The student wasn't identified.
That alleged conversation would have occurred at roughly the same time police have said Holmes began receiving "a high volume of deliveries" at his home and at the university. Police haven't said what those packages contained, but they said he ordered thousands of rounds of ammunition on the Internet.
The prosecution's allegation is the earliest report of a possible threat from Holmes, who was an enigma to many before authorities said he opened fire on a midnight showing of "The Dark Knight Rises" on July 20. Twelve people were killed and 58 were wounded.
Prosecutors allege Holmes also made unspecified threats to a professor in June, the same month in which they say he failed his year-end final. University officials say he left the program after the exam.
Holmes' attorneys argue prosecutors should have no access to his student records. It's not clear whether Holmes' attorneys filed a response to the prosecution's allegations. Most filings in the case are sealed and none of the defense filings released Friday by the judge address the alleged threats.
The prosecution motion was filed last week but not released by the judge until Friday, a day after a court hearing in which prosecutors first asserted Holmes had made threats. They didn't disclose any details about the threats then but did say professors had sought to keep Holmes out of their labs and "professors urged that he find another line of business."
A spokeswoman from the University of Colorado declined comment. Prosecutors and defense attorneys didn't return calls seeking comment.
Holmes' defense lawyer, Daniel King, has said Holmes is mentally ill and was seeing a psychiatrist at the university, setting up a possible insanity defense.
However, prosecutors are suggesting Holmes was motivated by his anger that he was failing at school.
Chief Deputy District Attorney Karen Pearson told the judge Thursday that prosecutors need access to school records to establish motive by showing what Holmes hoped to accomplish at CU and the "dissatisfaction with what occurred in his life that led to this."
