Gunman kills at least 12 in movie theater at "The Dark Knight Rises" screening in Aurora, Colorado

A Colorado gunman walked into a 12:30 a.m. showing of the The Dark Knight Rises, tossed a gas can into the crowd, then began shooting. At least 12 are dead, according to reports, with another 50 hurt.

The police took him into custody and are searching for explosives at his apartment. Redditor iteg3r collated an exhaustive timeline based on local police scanner broadcasts, tweets, and TV bulletins as the night unfolded.

Update (830am ET): Local Colorado news provider 9News.com has a live stream of coverage that's more informative and watchable than what the US cable news networks are doing.

At least 12 have been killed, and at least 38 are confirmed wounded, according to Colorado law enforcement. Victims include a 3-month-old baby. The shooter, according to eyewitnesses speaking to local TV news reports, ran in to the theater, lit a "gas can," shot into the ceiling, then into the crowd.

President Obama, Vice President Biden, and the First Lady have cancelled presidential campaign activities today. Obama: "This is a day of prayer and reflection for the victims."

A suspect is in custody: James Holmes, a 24yo white male who is said to have been wearing a gas mask, a bulletproof vest. According to law enforcement, at least four types of guns were used in the shooting, including an "AK-type" assault rifle, a shotgun, and two handguns. The suspect also used a canister of what is presumed to have been tear gas.

Among the dead was Jessica Ghawi (aka Redfield), a young female sports reporter who narrowly missed being killed at a shooting rampage in a Toronto shopping mall last month. She blogged about that experience here.

I can't get this odd feeling out of my chest. This empty, almost sickening feeling won't go away. I noticed this feeling when I was in the Eaton Center in Toronto just seconds before someone opened fire in the food court. An odd feeling which led me to go outside and unknowingly out of harm's way. It's hard for me to wrap my mind around how a weird feeling saved me from being in the middle of a deadly shooting.
