I live in the Mobile Area and I am following the case pretty closely. If you all have any questions about the surrounding area please let me know.
To answer some questions:
She worked for PF Changs, the car was purchased on the same day she disappeared, she went to Dublins Pub on Old Shell road to celebrate getting a car finally. Her and a friend/s left Dublins to go to another location, most likely downtown Mobile, (Dauphin Street). At some point (All of this according to a friend) she realized she didn't have her phone, flashed her lights to her friend (male) in a separate car and pulled over at the shell station on Government Blvd. 2 cars pulled into the gas station, a couple of minutes later one of the cars leaves, a couple of minutes later another car pulls in, then after that both cars leave. According to the friend, he thought Danniella was following him but she never arrived back at Dublins. The phone has been located and turned over to the police. I believe it was found in the parking lot of Dublins, but not 100% sure.
There is surveillance video of this, but the police are not releasing it. Here is a Description of the video:
Exclusive: Surveillance video may show missing Mobile mother
In the video in the link above they talk about the GPS on her car going dead at the gas station or that there was never another ping after that. I'm not sure if the GPS pings when the car is started or if it is a constant connection.
Her car has not been located.
