Well, I was thinking maybe he's a delivery person.

The death mobile? hmmm.. I thought they said that last night's shooting was from a white Astro van.

"maybe he is a delivery person"

or maybe he plans his hits to coincide with
similar delivery/ service truck schedules.
Everyone watchin for the truck, he waits till truck is leaving target location then takes his shot. Sits watchin at a distance or leaves in something else, not in a hurry.
Maybe a similar truck in the area is his que.
