Fox News and the networks affiliate in Washington, D.C., are advancing a conspiracy theory about the death of former Democratic National Committee staffer Seth Rich, suggesting in two stories on Monday that Richs slaying may be the result of his supposed links to WikiLeaks.

The only named source in both stories is Rod Wheeler, a former Washington Metro Police investigator and Fox News contributor who has previously claimed that a national network of armed lesbians was roaming the country and sexually assaulting children . Despite his history of unreliable and unverified claims, it does not appear either Fox 5 or Fox News independently verified the sources he cited.

Police have said Rich was fatally shot in July during a botched robbery attempt. But Reddit users and online conspiracy sites were quick to argue that Rich played a part in WikiLeaks obtaining and leaking thousands of internal DNC emails implying that Democratic presidential nominee Hillary Clinton and the Democratic Party had him killed as retaliation .

Multiple sources have publicly contradicted this, however: The U.S. intelligence community released a report in January concluding that WikiLeaks obtained its material last summer from Russia-backed hackers working as part of a Russian effort to help make Donald Trump president.

Still, Fox News contributor Ed Butowsky hired Wheeler to investigate Richs death, according to MSNBC .

We now have an update on Wheelers probe, because Fox News and Fox 5 decided to publish his unverified claims. Wheeler has said he has anonymous sources within the police investigation who have seen evidence of ties between the former staffer and WikiLeaks. He has also asserted that Clinton and her allies, the DNC or the D.C. government must be covering up evidence of a conspiracy to kill Rich.

Fox News and Fox 5 didnt call Washington police officials before suggesting they might be implicated in a conspiracy to cover up a murder, a police spokeswoman told HuffPost. Theres no evidence that either outlet spoke to Wheelers sources or confirmed they exist.

But Fox News has pushed its story, which also cites an anonymous federal investigator whom it says corroborates Wheelers claims. Sean Hannity featured a segment about the Fox 5 report during his Monday show, and Laura Ingraham on Tuesday begged for follow-up reporting into the supposed links between Rich and WikiLeaks. Despite its thin sourcing, the story also still led Fox 5s website on Tuesday afternoon.

By then, the original headline on Fox News story Seth Rich, slain DNC staffer, had contact with WikiLeaks, say multiple sources had changed to Family of slain DNC staffer blasts detective over report of Wikileaks link. The storys first sentence had also been changed to reflect that Richs family had dismissed Wheelers claims, and a quote claiming that someone within the D.C. government, Democratic National Committee or Clinton team is blocking the murder investigation from going forward had been removed from the story.
