I don't believe these recent murders can be attributed to him but I do believe he is at the center of the mystery. Pattrige is to young. The first murders occurred in the late 80s and they called the perpetrator a boy if we say bp was in his mid thirties he would have been 12 or fourteen when they occurred it would be hard to believe a 12 year old could have polished his skills that well at least by himself. Stiles has been able to build an empire showing powers of secrecy and manipulation i believe he conjured red john up to be the enforcing arm of visualize. But he himself is to old to fit the description of a boy in the late 80s. He has claimed an intimate knowledge of red john on a few occasions. He also would have the skills to brainwash some one very quickly. I also believe bertram is involed maybe stile has dirt on him and trades that for info. Truthfully I believe at least four of the suspect have dawned the the red john name for some purpose.
