so from what I recall... Shawn Lucas was the process server, who served a lawsuit to the DNC for election interference when the emails were released. He actually live-streamed on facebook when he entered the DNC headquarters and lawfully served the lawsuit(don't have fbook anymore might take a real deep dig to find this one, but I know he livestreamed because I saw it first hand).  Not sure the details of rest of story but I believe he was also murdered
