A private investigator hired by the family of murdered Democratic National Committee staffer Seth Rich is shedding new light into the events that led to Rich's June 2016 death.

According to private investigator Rod Wheeler, who is a former homicide detective, evidence on Rich's computer appears to link the slain staffer to WikiLeaks.

"The police department nor the FBI have been forthcoming,” Wheeler told Fox 5 in D.C. “They haven't been cooperating at all. I believe that the answer to solving his death lies on that computer, which I believe is either at the police department or either at the FBI. I have been told both.”

When Fox 5 asked Wheeler if his sources have told him there is information that links Rich to Wikileaks, he responded affirmatively.

“Absolutely. Yeah. That's confirmed," said Wheeler.

While it has long been claimed that Rich's Bloomingdale neighborhood murder was likely a robbery gone wrong, it has been theorized that Rich may have been the source of the DNC emails leaked by WikiLeaks during the 2016 election.

According to Wheeler, police have been told to "stand down" on the case.

"I have a source inside the police department that has looked at me straight in the eye and said, ‘Rod, we were told to stand down on this case and I can’t share any information with you,’" Wheeler told Fox 5. "Now, that is highly unusual for a murder investigation, especially from a police department. Again, I don’t think it comes from the chief’s office, but I do believe there is a correlation between the mayor's office and the DNC[.]"

Adding to the speculation, the story was retweeted on Monday evening by none other than WikiLeaks founder Julian Assange:

Rod Wheeler isn't the only investigator revealing new information on Seth Rich.

Fox News is also reporting that a federal investigator has confirmed to them that Rich was indeed in contact with WikiLeaks.

Fox reports:

A federal investigator who reviewed an FBI forensic report detailing the contents of DNC staffer Seth Rich’s computer generated within 96 hours after his murder, said Rich made contact with WikiLeaks through Gavin MacFadyen, a now-deceased American investigative reporter, documentary filmmaker, and director of WikiLeaks who was living in London at the time.

“I have seen and read the emails between Seth Rich and Wikileaks,” the federal investigator told Fox News, confirming the MacFadyen connection. He said the emails are in possession of the FBI, while the stalled case is in the hands of the Washington Police Department.

The Federal Investigator went on to to tell Fox that Rich was, in fact, the source of the DNC Emails revealed by WikiLeaks.

"The federal investigator, who requested anonymity, said 44,053 emails and 17,761 attachments between Democratic National Committee leaders, spanning from January 2015 through late May 2016, were transferred from Rich to MacFadyen before May 21," reports Fox.

If Fox's reporting is accurate, it would mean that DNC emails were leaked internally and not obtained by Russian hackers, as has been widely reported. It's worth noting that the DNC denied the FBI's requests for access to the servers it claims were hacked. To date, the only evidence that DNC servers were hacked comes from analysis by a third party security firm called CrowdStrike, which was hired by the DNC to investigate the breach.
