It's all CIA/deep state style and is repeated over and over. Without the fourth year med student at Howard Univ.Medical Hospital we would still be guessing.
From the post on the prior page it looks like the hospital where Seth Rich died was Washington Hospital Center, and the source of the info was a resident — ie., an MD in specialty training. But the interesting part is that the news reports at the time all referred to it in general terms — as in “an area hospital”, not by name. Very strange.
