That's not far off I-10 as you head northwest towards Phoenix. Marana would be described as rural, although it's trying not to be, but not remote. Red Rock would probably fit the description of remote.
The simplest and most likely explanation is she was deceased well before she was disposed and was not kept alive for some period of time. Occam's Razor.
The private security truck or van was patrolling. The Celis' home was very close to the mall and other businesses. The security video shows the back of the Celis' home. The speeding truck almost hit a trash bin, not a dumpster. This was about an hour before the 911 call was made and 4 hours after the surveillance video showed several people "showing interest" in the Celis' trash bin (3:00 am).
They found the body "earlier this month," according to TPD. Earlier this month is less than 37 days ago. Counting the time to arrange the listing, that means the decision to sell was made at least a couple of weeks before the discovery. They would have to have known that the discovery was imminent for there to be a connection.
No, it's not remote at all. It's about 2-3 miles southwest of the Celis house.
Someone had to have told them where to look, based on what they are saying. Since they say it was due to an investigation, rather than someone just stumbling across the remains, that suggests to me someone who knows how she got there finally said something.
From this map, the closest, uninhabited site from the Celis home (where a body could be dumped with less risk) appears to be near Swan and Golf Links Road. That's where the police have dug on several occasions with shovels and picks.
