As far as anyone knows, at this point Holmes did not have a FB or twitter account. These two being the most popular among social networking sites. However, afaics, that does not mean that he did not have an online presence. For example, we learned that he belonged to both AFF ( link ) and match.com ( link ), under the gyms ClassicJimbo and Classic_Jim, respectively. While AFF and Match have been around for awhile, what about other dating sites that have been growing popularity? For example, PoF ( link ) or OKC ( link )? There are other types of sites as well. For example, we know that he made some of his purchases through eBay ( link ). All eBay members have profiles. And, of course, there are personal sites. Blogs, that sort of thing. Now that we know he did, in fact, write a manifesto of sorts ( link ), there is a possibility that he also put something online. And, hey. We are "web sleuths" after all. So, if it exists... well, you get the picture. That said, before we don our web sleuthing hats and head out into the wilds of inet looking for bits and bytes that might help fill in the blanks to the Q, "who is James Holmes?", a cautionary. Peekyou <modsnip> includes links to the profile, ldmaster. Early on, many thought he was the shooter. As it turned out however, he was an older "tea party" former cop, and not our shooter. <Modsnip> The purpose of noting the Peekyou bit is, of course, is to urge caution if you do think you've stumbled upon the guy's online presence. Check, check again, and triple check. Oh and. Of course, save a cache of the material, just in case.
