A teacher at an Arizona prison was stabbed and raped by a convicted rapist after being left alone in a room full of sex offenders, according to documents obtained by The Associated Press. The teacher was administering a high school equivalency test on January 30 to about a half-dozen inmates with no guard nearby when the attack occurred. The Department of Corrections issued only a bare-bones press release after the attack, but the AP pieced together what happened based on interviews and investigatory reports obtained under the Arizona Public Records Act.
