Earlier today I listed some questions about Tyler Robinson about which journalists should be finding answers. One of those answers has subsequently emerged.
After spending one term at Utah State University as a pre-engineering scholarship student, he dropped out. It's reported he has spent the last three years at Dixie Technical College in nearby St. George UT, learning to be an electrician, one of the building trades.
At a guess, he had an unfriendly encounter with calculus at USU. He wouldn't be the first aspiring engineer to be baffled thereby. Don't ask me how I know.
Washington, where his family lives, is a suburb of St. George and living there is an entirely logical money saving step. St. George is a boomtown, with lots of new construction. Apprentice programs often involve actual installation work on construction job sites alongside journeymen electricians, which earned him actual paychecks.
So maybe Robinson wasn't even a slacker, he could afford his newish car. That only makes his being a murderer more improbable.

Later Correction ... Tyler Robinson was not living at home, he was sharing an apartment with Lance Twiggs, a person who may be transgender (photo) and who is said to aspire to be a professional gamer, presumably online. Twiggs ratted out Robinson's guilty-looking emails.
Inasmuch as Robinson didn't like his parents' Republican politics, this seems logical. I would guess the elder Robinsons would take an extremely dim view of a transexual flatmate for their son Tyler, perhaps he didn't share that datum with them.
Still Later ... A New York Post column alleges a possible homosexual relationship between Robinson and Twiggs. If accurate, that would go a long way to explaining Robinson's dislike of Kirk. Kirk didn't view trans as yet another category of "normal."
Being gay also accounts for Tyler girlfriends not surfacing. And could also explain his not doing an LDS "mission" before college. I doubt being both gay and LDS is any sort of easy or pleasant.
Twiggs and Robinson were part of an online group of gamers which included a number of grads from Robinson's high school. The FBI should look at the group for accomplices. Members may view Robinson's act with favor.
