It would be quite a leap to claim the story is bogus for the following reasons.
1.Uhhh.... Rich is dead in case you didn't notice.
2. A class action suit is underway by donors of bernie sanders for 85 million to get there money back since Sanders was indeed defrauded by hillary/dnc. the scam was basically what amounted to two sets of books. One the real one and the other one with her voters substituted for Bernies so he could not possibly have beat her in the primaries.
3.Julian Assange is the only one who knows who leaked the DNC info to him. He has worded his support of Seth Rich(played over and over by Hannity) as a leaker and the danger he endured in such a way that only the purest of dems would think anyone else did it,such as the ruskies for example,had done the leaking.
Rich was secretly a hardcore Bernie supporter,with lots of evidence for that claim.
If all that doesn't lend toward motive for the DNC to take him out including Podesta's claim that whomever did it will pay, then cirumstantial evidence doesn't exist.
We have a body,murder,law suit, and now motive.
4. The way things were handled at the hospital and the e-mail form the fourth year surgical resident is compelling.
Especially since the med person did not know at the time it was Seth.So you have a "blind" witness coming forth with compelling info on how rich was murdered a second time.
I could go on but if you are not convinced now.....
