I would say the unspent bullet linked to RA’s gun is the only physical evidence they have that we know of at this time. We know absolutely nothing about evidence collected from the crime scene other than that unspent bullet. and LE and Ives said there was a lot of it.
The prosecution has a tight timeline of witnesses, security video, etc. Again that is only what we know they have. That being said, the witness testimony is corroborated by RA himself which is kinda extraordinary.
RA’s initial interview with LE right after the murders contained very little information. He says he was at the trails, gives approximate times, saw no one but the three teen girls, was checking the stock ticker on his phone.
It was not until LE interviewed him again in 2022 that he discusses what he was wearing and that he actually was on the bridge. Important information he left out.
LE had a witness very early on that had seen a man on the bridge standing on the first platform. This person saw no one else. This witness walking away from the bridge passed two girls believed to be Abby and Libby on their way to the bridge. RA, in 2022, admitted to being on the bridge standing on the first platform. To me, this is the most important circumstantial evidence the prosecution has, again, that we know of. In 2017, a witness saw only one man on the bridge just before the girls got to the bridge. In 2022, RA places himself in that exact spot.
For 5+ years LE begged for tips and specifically a name. I always thought that was odd. Give us a name. Another way of saying, “solve the case for us” I thought. It makes sense now. LE had evidence early. My guess is they tried matching a lot of names to that early evidence and it never matched. Then they got RA’s name and things started to match up, witness statements, timelines, security video, unspent bullet. The last piece of the puzzle.
I am fairly certain they have the right guy. I do not believe anybody else was involved with the murders themselves or someone would have been arrested by now. RA has every reason to rat out any accomplices, but he hasn’t. I kinda doubt anybody was helping him after the fact conceal things for the same reason, no arrests. I do think there were people who might have wondered about if RA was involved but rationalized it away. That’s unfortunate, but it’s not a crime.
RA is apparently not taking well to prison. My thoughts are that there is a lot more d@mning evidence that arrives at RA’s attorney’s offices everyday.
Sorry this is so long.
Just my thoughts as I impatiently wait for a trial or a guilty plea(which I think is very possible).
