Yes, there is a news source (linked upthread) that shows his Arkansas license started October 2024. So, at the beginning of last school year, he was making plans to move to Arkansas for this school year.
Not sure what to make of that, but I admit my thoughts are not kind ones. Did he make sure he had the next job lined up, which gave him some free reign in the current job to mess up?
It does make me think he was particularly vicious in Devil's Den because if he got caught, then he'd lose his job. He had to prevent that, so killed rather than just run away. (Which, of course, was a stupid decision, but he made a series of stupid decisions).

If you look at the database his licenses were in green (or blue, I'm going off memory). But there was a note that all licenses in there color are reciprocity licenses. Arkansas and Oklahoma have some reciprocity for teacher licensure, meaning teachers certified in one state may be able to obtain a license in the other without having to repeat all requirements. So the Oct 2024 date was probably when he got his Oklahoma license. JMO
