When Deedee took Nader to visit her mother, the idiot doxxed her full name by filming the doorway to her room. So this led people to her Facebook. Can confirm there were old photos of the mom cooking in the condo kitchen. This, I believe, led to speculation that the condo was owned by the mother, not Deedee. I didn't SS the photos (sorry), but I checked at the time of this posting and the photos have been removed.
This isn't definitive proof, but it really did look like the mom was in her own kitchen with her apron on and all smiles.
