 Investigators say they have not yet uncovered a motive and so far believe Crooks acted alone. He was a registered Republican and did make a $15 donation to a progressive organization in 2021, according to the Federal Election Commission. Crooks worked at a nursing center and was a member of a local gun club. He was rejected from the rifle team in high school because he was a bad shot, according to fellow students. I don't think anyone would have thought this.
