In October 2012, former Shattuck-St. Mary's drama teacher Lynn Seibel was charged with 17 counts of criminal sexual conduct in relation to sexual abuse, both in class and in the dorm where he was a dorm parent, of six male students between 1999 and 2003. The abuse included group masturbation, naked dance parties, and in-class viewing of pornography, and targeted young men in the school's hockey program. SSM had dismissed Seibel in 2003 following the discovery of more than 14,000 pornographic images on his work computer, including images of minors, but ESPN's Steve Delsohn concluded, after a 7-month investigation, that the school failed to live up to its reporting obligations. Per Delsohn's 2017 report for ESPN's "Outside the Lines," although there was no legal requirement for the school to report Seibel's possession of child pornography, "school officials are mandated to report child sex abuse if they suspect it. By the time they found all the child pornography, there had been multiple reports of naked dance parties—a bunch of teenage boys naked with Seibel with them. There was the allegation and the report to the school that Seibel had sexually touched at least three Shattuck students. Years later, when then-headmaster Gregory Keifer was being deposed as part of the litigation, he said the red flags were flying that Seibel had a sexual interest in students. Then they find the child pornography, and a lot of it. At that point, if you suspect child sex abuse, and you are a school official, you are mandated to report it." An independent Minnesota Public Radio (MPR) investigation reached the same conclusion: "an MPR News investigation has found several teachers and top administrators did know about some of Seibel's alleged sexual behavior but failed to notify police." Per the criminal complaint, Seibel told police that the school was aware of his sexual behavior, and that interim headmaster Dennis Brown had told him, "Lynn, you're a sick man. You need to do something about it."
