They've botched this up so bad, here's an interview with the detainee's mother in law, the car is registered in her daughter's name, he's a delivery driver and the Mother in Law said she gave a consent to search so why the big drama over the court ordered search warrant.
Her name is Josefina Maddox, her daughter Jocelyn, who is listed to live at that address and at an address in Nogales is married to Carlos Palazuelos, the Carlos mentioned. He's 36 years old and has addresses in Tucson, Rio Rico, including the 425 Camino Agosto house they are currently searching, according to public records.
She has an active FB profile with a photo of the two

At the zillow listing of the house, which hasn't been sold since '92, the Nissan Rogue in questioned is out front in the driveway.
Additionally, a property in Tucson listed under many Palazeulos including an Alejandro (maybe a brother?) who is listed to work as a delivery driver too is about 30mins from Catalina Foothills.

This is the google view of Alejandro's house
