On the evening of December 14, 1992, 18-year-old Galen Gibson, a sophomore at Simon’s Rock College in Great Barrington, Massachusetts, was fatally shot while leaving the college library. The attack was part of a shooting spree carried out that night by fellow student Wayne Lo, who left campus after killing a professor, Ñacuñán Sáez, and wounding four others before surrendering to police.

Earlier that day Lo bought an SKS semi-automatic rifle at a sporting goods store and had received a mailed package of ammunition. He later told authorities he believed he was hearing commands from God to punish sins on campus; he was tried and convicted of two counts of first-degree murder and multiple counts of attempted murder and assault, receiving two life sentences without parole.

Galen was remembered as a student with a passion for poetry and theater. His father, Gregory Gibson, investigated the events surrounding his son’s death, wrote Gone Boy: A Father’s Search for the Truth in His Son’s Murder, met with Lo in prison, and helped establish The Galen Gibson Fund to support victims of gun violence and advocate for stricter gun laws.
