According to the "Disappeared" episode her dad wakes up ~7am and notices tracking is off on her phone.
She is dropped off by rideshare ~6:30am
If she was abducted wouldn't her phone have kept tracking unless perpetrator/s somehow disabled tracking before 7am?
I'm wondering what the last time stamp was that she was seen on a bridge camera alone, presumably safe?
This had to have been a very short window of time before her dad woke up and saw that her phone was no longer tracking
Although probably not possible it would be extremely helpful to get the exact time her phone stopped tracking and why (disabled, uninstalled, turned off...)
