Give us a sense of what Maria told you she felt in those early moments of just not hearing from her daughter.

She was desperate.

She shows us the texts and, uh, and you saw them, and where she says, uh, "Mija," you know, "My daughter, where are you?" You know, "Mi amor, where are you?" Uh, and she keeps, uh, reaching out to her, and there's no response.

But as it turns out, Susana had a friend named Kaya, and Kaya, Kaya had downloaded this app called Life360, and it's a, it's a popular GPS, uh, based app that tracks real time locations of people on their phone, people who give permission to each other to do this, families and friends.

And on that app you can see her phone at least leaving Kelly's apartment complex at around 10:00 PM, so it wasn't that late.

And you can actually see, uh, Susana starting to move, to walk home on Singleton, uh, Road toward her street, which was Santa Ana, uh, Drive.

And then Susana's phone starts moving in the opposite direction, and it's going very quickly, around 40 miles an hour.

What are they theorizing about what might have happened?
