Two Arrested, Charged Federally in Harvard Medical School Explosion Case
Two individuals were apprehended in connection with an explosion at Harvard Medical School (HMS), which occurred on November 4, 2025. The explosion took place at approximately 3 a.m. inside the Goldenson Building, specifically on the fourth floor, which is home to research laboratories.
Details of the Incident
The explosion, reported by the Harvard University Police Department (HUPD), prompted an investigation that led to the arrest of the suspects. Surveillance footage captured images of the two fleeing the scene shortly after the incident.
Suspects Identified
- Logan D. Patterson, 18, from Bourne
- Dominick F. Cardoza, 20, from Plymouth
Both men face federal criminal charges for conspiracy to damage an institution receiving federal funding through explosive means. The charges stem from the alleged use of a Roman candle firework, which detonated inside a laboratory locker, exposing the potential risk to life and property.
Investigation Insights
U.S. Attorney Leah B. Foley shared information about the ongoing investigation at a press conference. Although a motive remains unclear, evidence suggests that Patterson and Cardoza likely attended Halloween festivities at nearby colleges before returning to the HMS area.
Witnesses reported that the suspects presented a video of the explosion shortly after it occurred. The FBI’s Boston office confirmed that the incident was deliberate, but additional explosives were not found on the premises.
Public and Official Reactions
FBI Special Agent Ted E. Docks stressed the seriousness of the act, acknowledging its potential to cause injuries had the building been occupied. HUPD interim chief Denis G. Downing did not take questions during the press conference but highlighted the rapid response of law enforcement.
Aftermath and Safety Measures
The Boston Fire Department’s Arson Unit conducted an assessment, determining the explosion was intentional. Fortunately, no injuries were reported, and only minor damage occurred to the hallway. The building was reopened to affiliates with no long-term structural concerns.
As the investigation continues, authorities are gathering further details. The suspects were identified through public assistance after images were released, demonstrating the community’s engagement in ensuring safety at HMS.
