WikiLeaks founder Julian Assange has hinted that Seth Rich, who was a 27-year-old staffer at the Democratic National Committee (DNC) was the source of the leaked controversial DNC emails. He made this comment during an interview with Nieuswsuur, a Dutch television program.

WikiLeaks is responsible for publishing the thousands of leaked emails that showed the DNC favoring Hillary Clinton and trying to undermine Sen. Bernie Sanders. This lead to the resignation of DNC Chairwoman Debbie Wasserman Schultz.

“Whistle-blowers go to significant efforts to get us material and often very significant risks,” Assange stated in the Dutch TV interview. “As a 27-year-old, works for the DNC, was shot in the back, murdered just a few weeks ago for unknown reasons as he was walking down the street in Washington.”

On July 10, a Sunday, around 4:19 a.m. Rich was shot multiple times walking to his apartment in the Bloomingdale neighborhood in Northwest Washington, D.C.

Police have suggested the crime was an attempted robbery, although nothing was taken from Rich, according to The Hill.

Assange pushed back against this theory for Rich’s murder.

“No,” Assange responded. “There’s no finding. So… I’m suggesting that our sources take risks.”

When pressed on whether or not Rich was the person who leaked the DNC emails to WikiLeaks, Assange stated his organization won’t reveal their sources.

WikiLeaks is offering $20,000 for any information that leads to a conviction in the murder of rich, and D.C. police are also offering a reward of $25,000 for any information that leads to an arrest and conviction in the case.
