"First responders to the Aurora theater shooting at first thought the shooter was a fellow officer, and the shooter had taken 100mg of Vicodin about two and half hours before the shooting, according to information from sources." [ABC 7 News Denver]

Dark Knight shooting suspect James Holmes graduated in 2010 with honors from the University of California, Riverside, where he majored in neuroscience. University Chancellor Tim White remembers Holmes as a brilliant student.

Earlier this evening, The Dark Knight Rises director Christopher Nolan issued the following statement regarding the Dark Knight shooting in Colorado:

It hasn't even been 24 hours since a gunman opened fire on a crowded movie theater in Colorado and you can already predict the entire, familiar scene: the days and days of arguments about gun control, about mental health treatment access, about violence in movies and television. And, of course, the angry accusations that one person or another is "politicizing tragedy," unquestionably the worst sin in post-tragedy rhetoric.

North America's two largest movie theater chains, AMC and Regal Cinemas, released statements Friday afternoon updating their policies on acceptable theater attire.

Just weeks after The Today Show booted Ann Curry off its couch because she wasn't good at chitchatting with the fun, popular kids, the show, realizing no one on its current roster is capable of manifesting gravitas, has come crawling back to her.

This is one of those days where something terrible has happened and we're left to digest both the tragedy itself and the Internet's own messy response to the tragedy, a response that is equal parts informative, vitriolic, sympathetic, self-absorbed, and at times utterly unnecessary. Lost co-creator Damon Lindelof found out how hard it is to navigate such choppy waters when he sent out this tweet earlier today:

A shooter walked into a late-night showing of The Dark Knight Rises early Friday morning in Aurora, Colo., and opened fire. James Holmes, 24, killed 12 and wounded dozens more. Read our initial report here and catch up on the following stories on the Dark Knight shooting:

Warner Brothers is pulling the trailer for Gangster Squad — you can watch it above — from theaters, thanks to a scene in which a group of men open fire on a movie theater. (The scene starts around two minutes in.) A few months ago, Fox decided to change the title of its comedy Neighborhood Watch to The Watch after Trayvon Martin was killed in Florida by neighborhood watchman George Zimmerman. [LAT]

Authorities have identified 24-year-old James Holmes as the man who entered a Colorado movie theater early Friday morning and opened fire on a crowded screening of The Dark Knight. That's him above, in a photo from CU, where he was a student.

Who coud have killed 12 people at a midnight showing of The Dark Knight in Aurora, Colorado? Former FBI profiler Clint Van Zandt, appearing on MSNBC with Chuck Todd, speculates: "is this simply the terrible, terrible collision between some dark Trekkie-like person's fantasy world and reality?" Uh, Clint: no. [thanks to @ArkansasFred]

When there's breaking news, especially about terrorism and national security, ABC News' Brian Ross is there. And under no circumstances should you listen to anything he says. His latest breathtakingly reckless report: Some Tea Party guy on the internet has the same name as the Dark Knight Rises shooter, so, you know, they have the same name. So there you go. Tea Party.

Reddit user "themurderator" posted a series of images of himself after he was wounded in last night's Dark Knight shootings in Aurora, Colorado.

As people cast about for some explanation for the horrific shooting in Aurora, Colo., rumors have spread on Twitter and other social networks that the meme-swapping message board 9gag was somehow responsible, and that the 24-year-old suspect James Holmes had posted about his plan to shoot up a theater yesterday. They're almost certainly false.

Warner Bros. has cancelled Friday's premiere of The Dark Night Rises in Paris and pulled the cast and director Christopher Nolan from media interviews following the Colorado shooting.
