WASHINGTON - The Democratic National Committee is honoring a young staffer who was shot to death near his home in northwest over the summer. The DNC is dedicating a bike rack outside its headquarters in memory of Seth Rich. The 27-year-old was gunned down in July in the Bloomingdale neighborhood of Northwest D.C. Investigators believe his murder may have been the result of a robbery attempt. No one witnessed the killing and it remains unsolved at this time.
