Theories on what really happened between "Brandon", his victims, and Reid Ryan Allen. -One ridiculous theory posted by Vanessa Raquel Ling on her personal blog about the murders (June 18th, 2016) is that all of the victims are still alive (aside from Loren). She states "Brandon (as he calls himself more often than anything else) killed Allen, a kid who looked just like him, after Allen's sloppy murder, and then began posing as Allen in the videos so that he could actually help girls who wanted to run away, by making them appear to be dead on camera. Thus, explaining why not a single body has ever been found since Loren. And while Brandon was obviously getting off on this, even having sex with well underage girls, he was also helping girls escape lives that must have been far worse." Therefore this theory putting into question the families of these missing girls, which has caused further unwarranted destruction to their lives by the media and public. It's a theory which would mean that everything you've seen caught on camera, was actually staged, causing this to be the greatest hoax in the history of missing persons cases.
-The other and most common theory was published byTrue Crime Fanaddicts (June 12th, 2016); "Brandon 'mentored' Allen, simply so that Brandon could get away with murder. He aided Allen in killing Loren, but let Allen leave all of his prints behind - while Brandon left no evidence of himself - along with Loren's body and the video of Allen and Loren having sex (the video ended before Loren's murder occurred - the first and second girls to be recorded are actually the only two victims who are not murdered on camera). The 2nd video (of a man having sex in a car with victim#2) also features Allen on camera, not Brandon, as Brandon is the one behind the camera filming them. Brandon killed Allen shortly after this 2nd murder occurred. This would make sense since this video was shot near the construction site where Allen's body was found. After murdering Allen, Brandon began murdering the girls himself. Or perhaps Brandon killed both the 2nd victim as well as Loren, while Allen watched and learned." It should be noted that the second victim is one of the only three girls who have not been identified as her image was too unclear for anyone to make out. Also note that this site claims "Brandon may also have been the cameraman in the rape of Maria Bianchi."
-Additional theories; 1) Brandon is probably much older than Allen, many believe he could actually be 7-10 years older, which would have made him 23-26 years old at the time of Loren's murder and 36-39 years old today. 2) The murder of Karen Cassel was recorded by a 3rd party. When it was discovered that Alex Hartley was a victim of Brandon's, it was originally believed that Hartley was a witness who tried to intervene. However, the motel room Cassel was murdered at was never identified and some believe that it may be a motel near the location where Hartley was beaten. This would mean that there is a strong possibility that Hartley was the unidentified camera operator of Karen Cassel's murder. Whether or not he knew of Brandon's plans to kill Cassel will probably never be known.
Since crime scenes were never discovered until weeks, months, or even years after the murders (and some locations still have yet to be established), all kinds of prints would be found at the scene of each crime (especially at the various motel sites; as dozens, if not thousands of people would be in and out of the rooms before the FBI identified the locations), but prints of Allen, which is what they'd be looking for, would never be uncovered. Brandon, in fact, appears to have no prints on file, and possibly wiped down everything that he touched (though he never videotaped himself doing it). The guy is a mystery man, and apparently far smarter than anyone could have anticipated. Allen was simply a pawn in his game. If Brandon has ever been detained for looking like Allen, he probably just showed his real I.D. (or fake I.D., nobody is sure of anything right now as far as to what Brandon's real name could be), reacted calmly, and never had evidence or anything suspicious on him to take things any further. This could also explain why he killed with his bare hands, or anything that he could get his hands on. He never carried a weapon, rope, duck tape, cuffs, or anything at all that could be potentially discriminating against him (something Ted Bundy specifically would be questioned about when pulled over). This also might explain why he recorded the murders onto VHS tapes for the public; as a way to document the killings, keep the murders fresh and alive, without having to hold onto the tapes himself.
Brandon is the Boogeyman. Hiding in plain sight. And he could be anywhere.
