If I am reading the dates correctly on stories, RPSuch had a score of stories but has not filed a new one since 2011. I could not RPSuch listed in the list of missing authors. And "Circumstantial Evidence," a story mentioned by the author at the bottom of another story - I find no such story on SOL.
I confess this all be my limited search skills. Is there any word on this author? Or the story "Circumstantial Evidence"?
According to his author page, he posted his last story in 2010 and concluded it in 2011.
Circumstantial Evidence is not listed on his authors page. If he posted the story, he obviously removed it or it was removed for some reason. There is also the possibility that you read the story on a different website.
RPSuch aka Peter Schulman.
He also had an account on lit as rpsuch, but "Circumstancial Evidence" was also not posted there.
He had a web site www.peterschulman.com where he sold that story and hosted 23 sample chapters. That site expired in 2020 but is reachable via the wayback machine.
A search of "Peter Schulman" "Circumstancial Evidence" will give you some purchase options.
Also, he abruptly stopped posting the latest series he was writing at the time (He Said She Said) even though saying he was actively working on it. Too bad, it was really promising, I would have loved to read more of it.
Also, The Revenge of the Nerd he wrote is really good. Has anyone tried his gumbo recipe?
The story, Circumstantial Evidence, is mentioned at the bottom of RPSuch's "Insubordination," which is on SOL. Using the search suggested by Gauthier, I found both "Circumstantial Evidence" and "Circumstancial Evidence" listed for sale - with all but one of the listings saying it was no longer available. The one that appeared to still be available offered a pdf version for more than $100, beyond my meager means for a single story. I'm guessing, in spite of it being mentioned by the author on SOL, the story probably never made it to this site.
