Actually I was thinking “Suspect B” would be the person who let “Suspect A” into the theater.
“Suspect C” should be the person who sent the text demanding “Suspect A” be released or there will be more violence.
I’ve seen reports about him being let in, I’ve also seen reports about him leaving thru the door, wedging it open, then returning to begin shooting. I’ve not seen anything concrete either way so, whether a “Suspect B” would be the person you mention, someone else who helped (possibly with the explosives and booby trapping his apartment, or in some other fashion, I was expecting to read about a second (if not more) suspect.
In your “one-size-fits-all” world, how do you explain bi-polar children who have never been near pot?
