Normally there aren't vehicles parked on NG's street at night.
Given his planning, I'm not sure that this perk would have parked on the street. I'd be more inclined to think that, after smashing the back lights and disabling any cameras, if he was operating alone or perhaps even with a partner, he would have pulled in the straight driveway all the way up to the back yard and temporarily obfuscated the license plate.
But, somebody either saw a truck or there was a truck on somebody's ring or nest cam since LE were asking neighbors about a truck.
LE also seems interested in cars similar to SUVs but it could just be those are the vehicles driven by AG, SG, LD and possibly CP.
It would have been smart -- and since he was big into careful planning -- to have rented a a truck or vehicle that wasn't new or particularly noticeable from a private renter. Perhaps to have rented it for a week or 2 weeks so the person renting the vehicle wouldn't make the connection. He could have gotten a fake ID, paid in cash and rented the vehicle in Phoenix or a non-Tucson place.
Given his planning, I think he used a vehicle where he thought that he couldn't be traced to that vehicle.
All MOO.
