Missouri Attorney-General Andrew Bailey demanded that the 15-year-old facing assault charges in juvenile court be tried as an adult and hit with homicide charges if Ms Gain dies.

“This evil and complete disregard for human life has no place in Missouri, or anywhere. I am praying for the victim,” Mr Bailey said.

The Hazelwood School District also bears an “enormous amount of culpability” over Ms Gain’s critical condition in part because it had pushed diversity, equity and inclusion (DEI) initiatives over student safety, the state’s Republican AG claimed.

Mr Bailey said the district booted uniform officers from its schools after the police agencies refused to have cops undergo its requisite DEI training.
