Saffire Inc. was a third-party game developer. It was based in Pleasant Grove, UT and had a satellite development team in Saint George, UT. I was hired after Roger left in 2000, and can therefore make this claim with authority. Google can't tell an itching sarcastic everything he wants to know in order to make a wisecrack, nor is the Sun too diligent in finding out facts before making assertions.
Roger did not function as an advertising illustrator there, rather he was a 2D production artist. He mentioned that he felt like a square peg trying to fit into a round hole while there.
Read OldFartArtist and rogercarpenter comments and you can guess why he may have felt that way.
From a design standpoint, he was amazing, but lacked the digital expertise that his younger and less accomplished superiors posessed. Well, there's the state of the whole industry as it relates to phenomenal illustrators from yesteryear that are trying to make a go of it in a revolutionized creative environment.
I met Roger a few times and a few of the other artists from Saffire continued to keep in touch with the man for years after we were all laid off (post-911). For skill and creativity, Roger was a warlord among illustrators. I've only seen a handful of samples, and they are top-notch.
Unfortunately, this bean dip he was cooking may just be spicy enough to put him behind bars for the rest of his days. I hope he doesn't have to go there, but I don't see how a man can generate (if he actually did it) a poison that is this lethal and cart it across the country. A gun is used for self-defense. Poison has to be administered. It's a good thing he isn't dead, or worse, that someone else didn't die from exposure to the toxin.
