I know they said driver cleared, but who else could it be? Why would anyone get dropped off in park in the middle of the night? If she was meeting someone then she could have been dropped off at her place and driven her car or they could have swung by her place to pick her up. Unless it’s a married guy who doesn’t want anyone to recognize him!? At that time of night, no cars out - so if any were then a residen outside video came era will have picked them up and LE will get the person.
She obviously had her reasons because that's what happened. She had to have entered the destination in her phone and the driver followed that destination. This is all recorded info. Driver can't lie about that. She entered the address in her phone. It would be pretty far-fetched to suggest the driver somehow wrestled her phone from her to enter the park address. Even if that happened (not likely), he would've had to have changed the original address she entered because when you access the app and order a ride, you enter your destination at that time. Just because you wouldn't have any reason to meet up with a ride at a park at 3:00 AM, doesn't mean others wouldn't. She did.
