I didn’t find any conspiracy theories on the interwebs.

The perpetrator is still on the loose, and the homicide detectives are currently investigating the case and will be looking at the surveillance video too. There has also been no disclosure of a suspected motive behind the attack, the authorities have also not revealed if the attorney and his mother or even the Uber driver were intentionally targeted.
At some level it appears to be intentional. Hit the car, hit people, tried to hit other people. Ot at least that's how it reads, the shooter was trying to hit the car at least. That's much would appear to be intentional.
Whether or not these particular individuals were chosen in advance, that is premeditated against these people, that hasn't been determined one way or the other.
I figure typical city of brotherly love random drive by, unless the Uber driver has some connection.
This was either a case of mistaken identity or - more likely - a random attack by a black thug just for the hell of it. We see that over and over these days. I don’t know if the perp could tell the ethnicity of the victims, but if he did, I wouldn’t be surprised if that played a role in the murder.
