Assuming all of BH's clues are credible and will be explained at one point............. i would like to point out something interesting. Back in the season finale of 2nd season,before Patrick enters that empty building, he makes a phone call to Lisbon telling her his location and that he will wait for her to arrive. However,he does wait a bit and then grows impatient ,then enters the building alone. My question is how did RJ track down those 2 psycho copy-cats? And better yet the only person who knew Patrick's location at that time was Lisbon......................... It could be Red John keeps tabs on Patrick's calls but that doesn't mean he's sitting around 24/7 eavesdropping on his phone calls? Red John is very careful and he knew nobody else was going to be there so he went there himself to confront Patrick and kill those 2. Any theory on how RJ knew the location is welcome.............
