This is from Miles site and one of his readers. I do not agree with every paper at his site,but each is thought provoking and he explains how he got to where he takes you. I have thought a couple of times of adding this one to the collection of his papers I have,but have just been too lazy,I keep seeing Riches name pop up here, so I will offer the forum this for consideration on Seth Rich, among other interesting subjects including Washington DC Police Chief at the time Cathy Lanier.

: According to a 4chan anon a while ago, Rich's wounds were not
: mortal, and he was stabilized in the hospital, and then he
: was sequestered. Official types showed up, and then he was
: declared dead. No death certificate has been released that
: I have ever heard of. It would have been a perfect scenario
: to take him dark. He might have been transported to a
: military hospital, perhaps, for recuperation.

: This would be a reason for everything the FBI has on Seth Rich

: to be declared a matter of national security, for fear
: something in the material would indicate he is still alive.

: This could be an explanation for the odd behavior of the
: family, who first wanted the shooting investigated and then
: did a 180. Besides Seth, they want to protect brother
: Aaron, who Assange apparently claimed was also involved.

: The 4chan anon subsequently deleted the posts in question, but
: they were archived.

: Here is my previous post about this, including the link to the
: archive, and the text of the anon's posts:
