CNN — The University of Colorado is releasing nearly four-thousand e-mails that were sent or received by movie theater massacre suspect James Holmes.
They reveal Holmes may have had a romantic relationship with a fellow graduate student.
And Denver news station KMGH reports sources tell it Holmes began fantasizing about killing "a lot of people" nearly six weeks before the shootings.
It also reports a doctor who was treating him decided against holding him for a 72-hour mental evaluation-- because he was in the process of withdrawing from the school.
Holmes is accused of killing 12 people and wounding dozens more in a shooting spree July 20-th at a midnight screening of the Batman film, "The Dark Knight Rises."
