By the way, I would propose that the shooter was actually near the upper-right corner of the Petco, at nearly the very upper righthand corner of its parking lot closest to Rt. 234.
My source asserted that specific spot in the parking lot provides a completely unobstructed view into the Sunoco gas lanes.
I agree...we have to allow folks to see the shooting angle as well as how they may get to the car for a quick get away
