A Republican lobbyist says he's offering a $100,000 reward for information relating to the death of a Democratic National Committee (DNC) staffer over the summer.

Jack Burkman of Burkman & Associates said Wednesday that he hopes the money will help clear up what happened surrounding the shooting death of DNC staffer Seth Rich in July.

“There are too many dimensions to the tragedy and none seem to make any sense. 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,” Burkman said in a press release.

“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," he said.

Questions have lingered for months after the DNC staffer was shot multiple times early in the morning on July 10 while walking home in his neighborhood in northwest Washington, D.C.

Conspiracies swirled last month after the transparency group WikiLeaks offered $20,000 for information in the case amid coverage of a leak of DNC officials' emails. Damaging emails from the DNC were released later in July.

Police, who suspect robbery as a motive, said last month that there was no evidence to suggest Rich's death had anything to do with his work at the DNC.

Police have also offered a separate $25,000 reward in the case.
