A Republican lobbyist is offering a $100,000 reward to anyone with information about the death of a Democratic National Committee staffer who was murdered in Washington, D.C., in July.

Jack Burkman is a Georgetown University Law graduate and heads up Burkman Associates LLC as well as the American Decency organization. On Tuesday, he announced a substantial pay-out for anyone who can lead police to the individual or group behind the shooting death of 27-year-old Seth Conrad Rich, who was shot multiple times in the 2100 block of Flagler Place in Washington, D.C., on July 10.

"There are too many dimensions to the tragedy and none seem to make any sense," Burkman said in a press release. "I hope the $100,000 in additional money will finally get to the truth of what happened here and will either debunk the conspiracy theories or validate them. But for the sake of Mr. Rich's parents, family, friends, co-workers and the D.C. community at large, the murder needs to be solved and those responsible held accountable."

The six-figure reward is a jump from WikiLeaks' $20,000 pay-out. Burkman said hopes increasing the reward will encourage someone to come forward and help law enforcement determine the motive behind the attack, which they say was not connected to the victim's work at the DNC. The Metropolitan Police Department is also offering as much as $25,000 to anyone who tips them off to the perpetrator.

Rich was originally from Nebraska and known as a rising star within the Democratic organization. His death came weeks before WikiLeaks leaked thousands of DNC emails, which hurt the party by creating the impression that leaders favored Hillary Clinton over Bernie Sanders from winning, which has caused some to wonder if WikiLeaks had been working with Rich before his sudden death.
