Aurora shooting suspect James Holmes reportedly raised serious red flags with his psychiatrist prior to the July 20 massacre, sources told Denver media outlets.

There are fans of everything on the internet. Even James Holmes, the 24-year-old accused of killing 12 and injuring 58 in the Aurora, Colorado theater shooting. What would drive a bunch of seemingly normal internet geeks to worship a mass murderer? To understand this, you'll have to journey to the dark heart of internet fandom.

Conspiracy theorists have already speculated that President Obama somehow orchestrated the massacre in Aurora, Colorado, but a political billboard in Idaho aims to link Obama and the shooter thematically.

Aurora shooter James Holmes isn't the first mass murderer with a Facebook fan page, and he won't be the last.

Law enforcement sources who spoke exclusively with FoxNews.com claim that a package with a notebook from Aurora shooting suspect James Holmes was sent to the University of Colorado Anschutz medical campus in Aurora care of a psychiatrist who also teaches at the school.

The immediate aftermath of any American tragedy offers a heady potential for vile ideas. Details are scant, speculation is still wide open, motive is easily assigned—and in the rush to scoop other outlets, journalists don't have as much time to investigate claims, arguments or citations.

Given that James Holmes is responsible for a massacre, calling his behavior "erratic" feels like an awful understatement.

Here's something that almost all the mass killers of the last fifteen years or so have in common: they've been called "nerds." James Holmes, who allegedly murdered 12 people in a crowded Colorado movie theater on Friday morning, was described as a "nerd" by his uncle within hours of the shooting. Norwegian mass murderer Anders Behring Breivik is, in the Telegraph, a "puffy-faced computer game nerd." Columbine killers Eric Harris and Dylan Klebold were "innocuous nerds," the Los Angeles Times claimed in 1999.

While some choose to debate about gun control or the state of healthcare for the mentally ill, other stalwart truthseekers have made it their mission to get to the bottom of James Holmes' massacre at a midnight showing of The Dark Knight Rises.

By contrasting the ease with which Aurora shooter James Holmes ordered guns and ammunition online with the rapid FBI response when a Muslim would-be terrorist in Aurora sent a single suspicious email a few years ago, Denver Post columnist Chuck Murphy states the obvious in his column today: this mass shooting might have turned out very differently if James Holmes had been named Ibrahim or Mohammed.

Holmes, 24, is in court this morning for his advisement:

The homemade explosives, incendiary liquid containers, and jugs full of bullets inside James Holmes booby-trapped apartment "show the intensity and focus" of the 24-year-old suspected of perpetrating the largest mass shooting in American history.

You can't have a national tragedy without at least one religious zealot crawling out of the woodwork and spouting off about the downfall of America. And lo, American Family Association news director Fred Jackson is up to the task.

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.

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.

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:

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.

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.
