Mike Zullo, commander of the Cold Case Posse, has corroborated the claims. That’s what this report is saying, though not as clearly as it could/should.
“The information that we got, which these people refused to step forward with out of fear, but shared afterward, came independently – they don’t even know each other – from distance parts of the country, that investigations of major media outlets [were planned] if they continued reporting,” he said.
No, B. He did not. He just repeated the same tired old claim and provided no evidence to back it up.
That is not corroboration.
