“Controversial” investigation?
It’s an unsolved murder.
Not to worry, the investigation is left to the FBI (under the authority of Debbie Wasserman Schultz's brother), and Capitol Police
and was determined to be a "robbery" attempt, where nothing was stolen (watch, ring, cellphone, money).
This would seem to be a second robbery attempt where the victim was twice shot in the back, but this time, the victim was then run over by a vehicle.
Nothing to see here,.. it's just another typical day in Washington in the Seth Rich murder investigation.
Move along, citizen... There's nothing to see here ! (s/)
