New conversation screencap between Guccifer2.0 and actress @robbin_young indicates that Seth Rich leaked the DNC emails.
Seth Rich was a DNC Staffer who was murdered in Washington D.C. in July 2016. He was shot at 4:20am and news reported that it was an attempted robbery, though nothing had apparently been taken from him.

I remember hearing gun shots that night at work as well. Next thing you know the local news reports about it, then it just vanished.
