Law enforcement officials say James Holmes, the suspect in the Colorado movie theater shooting, sent a package to a university psychiatrist about a week before his alleged crime, warning he would shoot people.
The officials say the package sat in the University of Colorado mailroom and was not discovered until after the July 20 mass shooting that left 12 people dead and 58 wounded.
The package reportedly included stick figure drawings of a gunman shooting people.
Holmes was a PhD student in neuroscience at the university before dropping out of the school. But the motive behind the massacre remains a mystery.
Holmes is being held in solitary confinement ahead of his next court appearance. He could face the death penalty if convicted.
Meanwhile, the first funeral was held Wednesday in the wake of the shooting. Gordon Cowden, who was 51, was the oldest of the victims.
