I was wondering the same actually, since this guy gets constantly recommended by creative and i never heard of him.
So i started to dig, because i was really, really curious about this. I looked through my own wrestling magazine/newsletter archive (90 gigs covering everything from 1951 to 2015, from local newsletters to PWI, so chances are very high that there would be a mention of the name at least). I looked on the RSPW archive, wrestlingclassics, general online searches and even downloaded a 400 page book named "Obituaries in the Performing Arts 2004" (he supposedly died in January 2004 in a car crash according to Cagematch), which does cover wrestler deaths and additionally looked for a car crash on January 25, 2004 and since the only other information is Iowa, i looked there. Not a single mention at all (but obviously he could've lived in any other place at the time of course) and i even looked for variations of the name, since "Rochr" sounds extremely weird to me, so i also looked for Roche and Rocher, which are way more common, but there was nothing to be found at all.
By now i'm actually convinced, that this person never existed. If the data on Cagematch (and that's the only site that lists him and they barely have any information) is correct, it is extremely strange that a wrestler, trainer and promoter, who was supposedly active for 25 years and died in a car crash, has not a single piece of information online. No pictures, no match listing, no info on the promotion he supposedly ran, no match videos and not even any info on the supposed car crash.
