I actually see it as less suspicious that it was such a busy area. If her car had been parked alone in a quiet, empty parking lot I think it might have been checked out by someone a lot earlier. It would have been noticed by a police officer, business/lot owner, security—someone.To me, what's the most suspicious about this whole thing is how long it took to find her in what seems to be such a busy area.
It made sense to me when I found out she was parked in Heubner Oaks with constant activity, people parking, getting in and out of cars all day and at night, rushing to get out of the intense heat. With the dark clothes she was wearing, it might have taken someone to physically walk over, cup hands against window and look in to find her. Since the car being there wasn’t suspicious in itself, it took the smell to become bad enough to alert someone to check it out.
