I live within 5 miles of Stephanie Hollingsworth (we attended the same yoga studio, may have been in the same aerial classes together but I don't recall as it's been several months due to covid).
The idea of her crashing into a waterway around here definitely crossed my mind and could still be a possibility, but just to give some more context of this particular part of Orlando --
It is nonstop sprawl, stoplights and traffic. There are lots of retention ponds and waterways, but there is no way that around the mid- to late-afternoon hours of Friday that someone wouldn't see an SUV going under or into some Brazilian Pepper. There have definitely been stories of people under the influence crashing and drowning in retention ponds off the side of a highway, but there has always been someone who sees the crash.
If she were to have driven 15-ish miles east on 528, there are plenty of wide open spaces without a soul in sight. I am hestitant to believe this only because:
1. It is a pain in the butt to have to sit through afternoon traffic, plus get on the highway that is full of construction (all of them are here), and drive out a few dozen miles to get to an area where no one would notice if something happened to you. Especially if we're implying she was under the influence. I would imagine she'd be driving somewhat erratically.
2. I'm also hesitant to believe she drove that far out of the way to drink. I think this was meant to be a quick trip (especially considering she had 3 kids who are all school-aged). I kind of get the feeling that her family was in the process of addressing her alcoholism, that she was possibly in the very beginning of recovery and thus was why she "required care". If you listen to the way her husband described her when a reporter asked about her "mental issue", he had a lot of difficulty with it. It possibly sounded like he and his family had just come to terms, or addressed it in a way that brought a new level of awareness or action -- it's so difficult to have to admit something to yourself, let alone then have to tell the world about it, especially when it then has to do with a missing persons case. Granted, all speculation on my part, we obviously don't have the full picture.
I say all of this because it makes sense why she may have left her phone charging at home. I don't know about androids, but iphones can track and share your location with others you allow. It very well could have been that she just forgot her phone, or didn't usually bring it with her on quick trips, but my thought was that possibly she intentionally left it at home because her husband (or anyone else in her family) could easily see where her location was. If she leaves it at home, for anyone who checks her phone, she 'is' at home. Which to me would suggest she felt this would be a quick trip to get money out of the ATM (cash means no tracking that she went to a liquor store), purchase the vodka, and probably go somewhere close by to drink and head home before her family got home for the day. I feel like there had to have been a favorite spot close by that she has been to in the past, that she's gone to before to do the same thing. I just don't know where. It could have very well been a crowded parking lot, but surely a security camera would have recorded something?
I'm really worried that there is foul play and not that she ran off the road somewhere. Knowing these roads (I drove the same route last night she took), I just don't know how in the world someone wouldn't have noticed. The only way it's possible is if she found a spot to drink, and hours and hours went by until it was the middle of the night. Either way, it's definitely troubling.
Some things remind me of another case when a mom of 2 young boys was missing/was last seen on video at a store, and later found her car hidden in the woods and found she had committed suicide. I hate to say this but it is just my gut feeling.
