The Colorado movie theater shooting suspect was seen in public at his first court appearance Monday after he allegedly opened fire at a midnight showing of “The Dark Knight Rises” on Friday, killing 12 people and wounding 58. 

James Holmes, 24, appeared in court dazed with dyed reddish orange hair, ABC News reported. He showed little emotion and was wide-eyed, frowning and unshaven. He went bug-eyed at times and closed his eyes at other times. 

The advisement hearing lasted about 15 minutes during which Holmes did not speak. District Attorney Carol Chambers is expected to file formal charges next Monday. According to The New York Times, Chambers has a reputation in Colorado for seeking the death penalty. There are currently three people on Colorado’s death row, two of them put there by Chambers and her team, ABC reported.

Holmes allegedly set off gas canisters and used a semiautomatic rifle, shotgun and pistol to open fire at the Aurora, Colo., movie theater, police told Fox News.

Police told The New York Times that they believe Holmes began planning the rampage months ago, acquiring the guns and ammunition used during the shooting and to rig his apartment with explosives. Aurora Police Chief Dan Oates said Holmes purchased 6,000 rounds of ammunition over the Internet, Fox reported.

Holmes has not been speaking to authorities since his arrest, The New York Times reported, and is being held in solitary confinement.

CNN reported that as of late Sunday, at least 17 people remained hospitalized, eight in critical condition.
