I have a red barn theory that id like to share with yall.
The bodies found in the barn were bound and tied up just like red john victims but it was way back in 1988. If red john committed those murders then we would of seem more murders like that before 1998. Serial killers don't usually take a 10 year break after their first kill..
I believe red johns friends or family were the ones that were killed but by somebody else . And this tragic event most likely created the monster of red john. Could it of been grace van pelts family or friends or maybe haffners ? I have no idea but i am pretty sure red john did NOT commit those specific murders due to the timeline.
