James Holmes had dyed bright red hair and told police he was "the Joker" when he was taken into custody after the mass shooting in Colorado Friday. Now investigators are asking, is he also ClassicJimbo?

Someone with dyed red hair, who looks strikingly like Holmes, posted a profile on an adult website on July 5. He said he lived in Aurora, was looking for "casual sex" or a "fling" and asked, "Will you visit me in prison?"

ClassicJimbo also claimed to have "some grad school" which would fit into Holmes' real-life resume. He had been working on his Ph.D before dropping out of school last month.

As Breaking Celebrity News has been reporting, Holmes opened fire in a packed movie theater showing The Dark Knight Rises, killing 12 and injuring another 58 Batman fans. He also left his Aurora apartment booby trapped and law enforcement has not yet been able to safely access it.
