Custodian's Warning: A Prelude to Tragedy at Brown University

Behind the Incident: A Warning Ignored

The tragic shooting at Brown University on December 13, 2025, which left two dead and nine injured, highlights a grim reality about campus safety. Derek Lisi, a custodian at the university, observed the alleged shooter engaging in suspicious behavior weeks prior to the incident. His reports to security suggest a significant oversight that begs further examination.

A Custodian's Vigilance

Lisi shared with The Boston Globe that he encountered a man he later recognized as the shooting suspect approximately ten times from early January. During these encounters, Lisi noted the man pacing through the Barus and Holley engineering building—fixated intently on classrooms and even hiding from view.

“When police shared images of the suspect, I knew he was the same man. He had been casing that place for weeks.”

The Harrowing Details

It's chilling to consider the extent of Lisi's observations. His initial encounter with the man occurred as early as January, but it was not until December that Lisi alerted a campus security guard. He described feeling uneasy about the individual's presence and behavior: circling hallways and constantly peeking into room 166, the location of the eventual shooting.

Investigating the Culture of Safety

With insights from Lisi's experiences, we must question: what protocols are in place to heed warnings from non-traditional observers? Security personnel often rely on reports from students and staff, yet Lisi's actions suggest a failure in communication within the wider campus community. This failure did not just lead to tragedy; it underscores a culture of complacency.

What Needs to Change?

As we move forward, it's crucial to advocate for a more robust security infrastructure on college campuses. Students and staff must understand that their observations carry weight, and systemic channels must be in place to escalate concerns efficiently. Here are a few recommendations:

• Training and Communication: Regular training programs for staff can help emphasize the importance of reporting suspicious behavior.
• Increased Surveillance: Monitoring high-traffic areas with enhanced security measures can deter potential threats.
• Community Engagement: Building a community where students feel empowered to speak up without fear of dismissal is vital.

Aftermath of the Shooting

The implications of that December day are profound. Following the attack, victims' families are left to grapple with loss while Brown University faces scrutiny over security lapses. With the university hiring former U.S. Attorney Zachary Cunha for guidance, it signals an acknowledgment of the systemic issues at play.

“I knew there was something off with him,” remarked Lisi after the tragedy. His insight highlights the importance of vigilance, but also raises questions about missed opportunities to act.

Reflecting on Violence and Vigilance

This incident serves as a vital reminder of the role every campus member plays in maintaining safety. In an age where mass shootings have become all too common, we must prioritize proactive measures and foster a community that does not shy away from intervention. As we reflect on the events at Brown University, it is imperative that we advocate for change and never assume that someone else will take action.
