Well dressed white man? Clark Kent, perhaps. Maybe he thought he could fly.National Harbor is in PG County. It was probably a random ghetto crime.
Really? How so, give us the scenario of how the well dressed white man ended up on the pavement dead. Did they take his wallet and watch? Got a link for that? How do you know all this?
Well, the OP's link said he was a well dressed white man. Here's the quote from the OP's link:
A witness, Muhammad Ilyas Khan, told the Examiner he was in his car and saw a man hit the ground from the parking garage. He described the person as middle-aged white male who was well-dressed.
