A mass-shooting during the midnight screening of  "The Dark Knight Rises" at a crowded movie theater has claimed at least 12 lives and injured 58 people in Aurora, Colorado. The suspect James Holmes (pictured above) is in police custody and is expected to make his first court appearance on Monday.

FOX News Radio's Rich Johnson reports on how events unfolded at the movie theater:

It was just about 10 minutes into the movie when the gunman kicked in an exit door near the screen, tossed a tear gas canister and started shooting.

Jennifer Seeger was in row two and saw the gunman way too closely.

(Seeger) "He had it to my face. He had the gun in my face. I was freaked out for like five seconds. And I just dove into the aisle and I was like I don't know what to do, I'm just gonna curl in a ball."

Police found the suspect, identified at 24-year-old James Holmes, outside the building.

They've searched his car and apartment for explosives.

News of the shooting at the Batman movie premiere in Aurora has moviegoers in other cities shaking their heads.

FOX News Radio's Jennifer Keiper reports from Chicago:

'Dark Knight' moviegoers here in Chicago walk out only to find out about what happened in Colorado.

(Moviegoer) "That's just terrible. We just all come here peacefully, try to watch a peaceful movie."

(Moviegoer) "It's not surprising to see that this can happen. It's very saddening."

Similar response from Warner Brothers and the filmmakers. Chicago Sun Times columnist Bill Zwecker tells FOX News Radio tonight's (Friday night's) Paris premiere has been canceled.
