Not sure if this is true, because never seen it talked about since... I only found the one reference that day and never could find it after... Putting it out to talk about it and not as any proven facts.
Day of the shooting, there was a reddit post that said this guy had two separate twitter accounts, and they had captured both sites and saved them offline immediately.
One had a bunch of pictures of him as a Trump supporter and the other had him praising ISIS... The claim was made one was deleted almost instantly and they left the other one up...
I saw the photos they linked for both, they both appeared real, and the same person, but I did not follow all the details of this shooting because I was wrapped up trying to find my way out of the maze of rabbit holes.
I did not see any of that. Is the information still out there somewhere?
4chan had them both that day
