CENTENNIAL, Colo. (AP) Security was tight Monday outside the courthouse where the suspect in the Colorado theater shooting was set to make his first appearance.

Uniformed sheriff's deputies were stationed outside, and deputies were positioned on the roofs of both court buildings at the Arapahoe County Justice Center in Centennial, south of Denver.

James Holmes is being held in solitary confinement in jail on suspicion of first-degree murder. He will be moved to a nearby courtroom for the hearing, where he will hear the pending charges against him. Prosecutors will have 72 hours to file formal charges.

Authorities say Holmes is refusing to cooperate and that it could take months to learn what prompted the attack that killed 12 and injured 58 moviegoers at a Batman film premiere.

Holmes grew up in San Diego. He enrolled last year in a neuroscience Ph.D. program at the University of Colorado-Denver, but school officials say he recently left the program.

Nineteen-year-old Marqece Phillips, a friend of shooting victim A.J. Boik, came to court hoping to get a seat to watch Holmes' appearance. Phillips was watching "The Dark Knight Rises" on a nearby screen the night of the shooting and rushed to the rampage site before the shooter left.

"I want to go see him and see his face. I seen his eyes through that mask," Phillips said. "I want him to see the pain in our eyes, to see what we're going through."

Phillips said he's had recurring nightmares about Holmes since Friday.

"Maybe it will put some kind of peace to me to think, OK, they got him, they got him, they got him," he said.
