Prosecutors say the suspect in the Colorado theater shooting made threats and was banned from the University of Colorado after failing a key exam six weeks before the rampage.
They made the accusations about James Holmes in court Thursday as they tried to convince a judge to let them see records from the university, where Holmes had been a graduate student.
Holmes, a Westview High School graduate, attended UC Riverside where he graduated a BS in neuroscience in 2010. He then went to Colorado where he was pursuing his graduate degree.
While in San Diego, Holmes lived with his parents Robert and Arlene Holmes on Sparren Avenue in Rancho Penasquitos.
Arlene Holmes, a registered nurse, works with Tri-City in Oceanside. The defendant's father, Robert Holmes, is a software engineer who lists his employer as Fair Isaac in the Carmel Valley area.
Prosecuters also claim professors had urged Holmes to get into another line of work before the shooting. Attorney Karen Pearson didn't disclose where their information came from, and prosecutors did not give further details on the nature of the threats.
Defense lawyer Daniel King objected to the release of the records, calling the prosecution's request a "fishing expedition."
Holmes is accused of killing 12 people and wounding 58 others in a July 20 shooting at an Aurora theater.
