I'm praying it wasn't a sadistic pervert (too much of that going around)
but a push down the tag along accidental kind of thing - they/he/she panicked, hid her, and then ran away/cover up mode.
Do not know details - did she sneak out at night time or was she up early on Sunday? either way could have been with others who did not want her around.
Parents slept in, woke up late, relied on older siblings or community kids were watching her - by the time dinner or after dinner time came realized somethings wrong.
It may have been 24hrs since last saw her - but it wasn't 24hrs of knowing she was missing before contacting 911.
If parents slept in/woke up late, what time would that be 10am, 12noon? Lets say they think w/other siblings and later on question siblings but siblings say idk maybe with community kids, what time would that be at ? 12noon, 2pm. Give a little more time, so far nothing unusual, made herself breakfast and went out to play. Maybe with other kids and had lunch by now. Let her play until dinner. So now it's like 3pm or 4pm so they wait until dinner. Is that at 6pm, 7pm? but they now start questioning because siblings have not seen her, she hasn't checked in, so they check around the neighborhood (8pm by this time?), and they had to have contacted at least one of the neighbors that she was missing. The neighbors are the ones who eventually called 911, maybe because the parents were distraught? That gives us timing at around 9pm (dad thought contact w/911 was made) 10pm was more accurate from news report.
In a way, maybe a very round about way, police were contacted when they happened to notice/realize she was for sure missing.
I believe the police know what happened, just have to get formalities and evidence taken care of. They are going to say what ever needs to be said, and at the same time say nothing at all.
To me, the father is not looking so good especially with his background - but there's still a little wiggle room that it may not have been him.
Given the police have yet to name him POI (or anyone), I went with the knock down tag along accident.
