I am highly suspicious of anything related to the killer. This looks to be a staged event, with the FBI manufacturing the narrative, and the MSM lapping up the Federal feeds. I don’t know whether the man was manipulated by a government actor to commit the murders, but it looks like the FBI had a script ready to go. I hope that someone who is tech savvy can detect whether the killer actually wrote the posts attributed to him, or if someone else did.
Definitely a planned, manipulated event.
