I think RA talked to the police mostly because he knew he had been seen on the trail.
What he didn’t know, however, was whether anyone who had seen him could identify him as Rick, who works at CVS. By going to LE himself, he seems less suspicious…what guilty person would put themselves at the crime scene(which is our question too, but he did).
Initially, in 2017, RA only talked about the three teens on the trail. It wasn’t until 2022 that he mentioned being on the bridge, probably after LE told him someone had seen someone dressed like him on the first platform. That scenario and admission by RA by itself makes RA a prime suspect and a darn good one.When that witness turns back up the trail, Abby and Libby are only minutes from RA, by his own admission, but he did not make that admission until he was confronted with the fact that he had been seen.
I think it’s interesting that when LE first put out the picture of BG they only wanted to talk to the guy on the bridge. He wasn’t called a suspect, just maybe he saw something. RA, who admitted almost six years after the crime to being on the bridge and dressed like that, never…in those six years, called LE to tell them that.
We are debating a lot about the worth of the evidence put forth in the PCA. To me, as a whole it’s pretty compelling.
I am positive though that LE has a lot more that we are unaware of yet.
