There has been some question about the timing of the first sister coming forward due to its close proximity to the announcement of a reward. According to some ideas, the sisters were taking advantage of their brother because he apparently has the mind of a seven year old.
Unfortunately, in this case, people seem ready to jump on board with any conspiracy theory that disproves the D's Odinist theory.
Personally, I have found many things in this case hard to believe, from 77 year old RL being the suspect, to keyboard jockey KAK, to a CVS worker with a clean criminal history, to DC's overtly religious talk, to RI's description of the CS being odd, to the two vastly different sketches, to the hundreds of strange coincidences, to the highly unusual treatment of RA as an in-custody defendant, to the judge's handling of the docket, to NMcL saying others could be involved and everyone ignoring that (yet putting merit to every other thing he says), to the weird FM, to the leaks, to a suicide, to Odinist guards allowed to wear patches and tattoos that could possibly tie to white supremacy in the prison system, to the SCOIN hearing oral arguments and ruling in less than four hours, and so on. The Chaos Theory is the only theory that makes sense to me anymore. Jmo.
