The perp could only be identified as a white male.
The guy shoots you several times from the front in a parking garage, but all you can say is he is white and male?
I assume the attacker uses a pistol because otherwise the millionaire would certainly be much more seriously injured.
With a pistol in a parking garage you would need to be less than 50 feet to have a clean shot (probably less than 25).
At that range the millionaire should be able to get a much better look at the attacker.
The police are not doubt withholding information on the attacker for some reason.
