In 1988, an Irish-born Catholic priest and a Marist brother were indicted on charges they sexually abused boys at the school. Irish Reverend
Bernárd Lynch, who served as the chaplain, and Brother Timothy Brady, the acting principal, were accused of molesting three boys. Lynch was acquitted while Brady was sentenced to prison. Following Brady's release from prison, Marist Brothers reassigned him to a Catholic high school in Chicago from 1993 to 2005. In 2011, Marist Brother Lawrence Gordon, the assistant principal, was criminally charged for possessing child pornography. Gordon accidentally left a USB drive plugged into a library computer on Valentine's Day, which held sexually explicit images of underage boys. Gordon pleaded guilty and was sentenced to a year at
St. Luke Institute, an institution known for treating priests accused of child sexual abuse. In 2019, Father Bernárd Lynch was accused again of sexually abusing a different teen student at the school 40 years ago, according to the lawsuit. The 57-year-old plaintiff, then a 16-year-old at the school, alleged the sexual abuse occurred in 1978 and 1979. The lawsuit was dropped in 2021. == Notable alumni ==
