Article about the STEM school shooting. (June? May? Not terribly long ago.)

(Needless to say, the information is difficult to confirm, and there should be some "allegedly" and "supposedly" and the like. I'm going to present details very briefly, and as if they were true, but only for simplicity. It will take some time to verify things, if it can ever be done.)
Highlights:
Both shooters were high on cocaine during the shooting.
The younger shooter, McKinney was the ringleader. He was seeking revenge against specific students who had misgendered him.
Both had a history of mental illness and drug abuse.
The elder, Erickson, was a reluctant participant, but kept getting pushed forward by McKinney. He told police after his arrest that he kept thinking he would reveal the plot, but he kept backing away, sometimes because McKinney threatened him. His last attempt, he claims, was actually at the beginning of the shooting. He charged into the classroom and told everyone to not move. He was, he said, going to warn them that the other shooter, McKinney, had a gun and was going to shoot, although McKinney said that was all part of the plan. The plan was that Erickson would tell them to stay still, and then McKinney would go into the room and kill specific, intended, victims.
So, not really a classic school shooting, in which a person decides to kill as many people as he can, with little regard for who gets killed. Exactly what it was is difficult to say, but we may never be able to know exactly who intended what. All we know for sure is that three people jumped one of the shooters as soon as he said anything, and one of those three ended up dead.
ETA: And I may have gotten some details slightly wrong. My intent wasn't to give an accurate account, but provide a few bits that might be of interest, and let people read the article for themselves if they wished.
