The Defense intended to use that data spuriously, as evidenced by their motions, to turn witnesses into perpetrators.
The biggest hole in the phone tower dump IMO is the absence of RA's phone. Of course some will say that's conformation he wasn't there, but or only shows that his phone wasn't.. And why would that be? Especially when he himself claimed to have been on his phone? That would have been the easiest way to exculpate him -- if it existed, if it were accurate, if it put him there magically from noon to 1:30 and sonewhere else after. It doesn't. It likely says his phone wasnt there at all, at any of the times.
Which the Defense didn't want to elicit under oath because the State would be all over that. Plenty of hood reasons murderers leave their phones behind.
And the State didn't need to make the point. IIRC the Defense did, in their opening statement, that there was no digital evidence tying him to the crime scene (also brought out on either Defense cross or Defense direct). The jury can connect that dot. His phone wasn't there. What that says or doesn't say, they can weigh.
Beyond that, there's just not much help from the tower dump.
From 1 until 4, there just weren't that many phones there and eventually they were all accounted for.
By 4, you've got park-goers that are in no way connected to anything, nearby neighbors who live there and so do their phones, and early searchers, bringing in theirs.
Fluke of flukes, in RA's favor for committing a crime in broad daylight and against two terrified little girls who had nowhere to turn, there was no one around at 2:14. Absolute echo chamber.
We can't know whether there was screaming or not. RA says there was. There well could have been. RL was gone, at the fish store iirc. The W family was away. BW was driving home from work. BB had just gotten in her car and left. Old guy with the camera maybe hadn't arrived yet, FSG might have been inside, doing his exterminator job, and the later walkers hasn't yet arrived.
If a child screams in a forest, and no one hears it, does it make a sound? Only three people were DTH. He says he heard screams so maybe he did. The girls can't tell us.
It just remains how absolutely dreadful it had to be, that for a sliver in time, at 2:14 until about 2:28 there was no one around who could stop this. Just RA unfettered. And he wasn't stopping for nobody.
Whatever happened, unless RA chooses to tell more someday, only the trees know.
Frankly, I'm okay if RA is forever haunted by what he did, in his ears, before his eyes. Indeed, does a good person kill two little girls?
No.
