"ANNOUNCE: WikiLeaks has decided to issue a US $20k reward for information leading to conviction for the murder of DNC staffer Seth Rich," the website tweeted.
Police have said it is possible that Rich's death was the result of an attempted robbery in the Bloomingdale neighborhood of Washington, DC, last month. The case remains under investigation, and police and the victim's mother appealed last week for tips on Rich's murder.
Rich's case has gained an inordinate amount of attention from some right-leaning outlets, which have posited without factual evidence that Rich's death was part of a larger conspiracy.
WikiLeaks, which appeared to fan those flames Tuesday, did not immediately respond to a request for comment.
Its announcement came several weeks after the organization revealed hacked internal emails in which top DNC staffers floated potential lines of attack on Sen. Bernie Sanders during a heated Democratic primary campaign. The FBI has launched an official investigation into the intrusion, which has been linked to Russian hackers.
WikiLeaks has come under fire in recent weeks for its blatant criticism of Democratic presidential nominee Hillary Clinton and relative silence about Republican presidential nominee Donald Trump. Asked about whether the organization was biased toward Trump, founder Julian Assange said the US election was the equivalent of choosing between "cholera or gonorrhea."
There appears to be little sympathy for the DNC within WikiLeaks.
When Business Insider suggested in a Twitter message last month that some individuals mentioned in the leaked DNC emails feared another round of leaks at the party's convention in Philadelphia, the organization had a succinct response.
"Poor babies," WikiLeaks responded.
City officials did not respond to Business Insider's request for comment.
