2 Men Charged in Harvard Explosion
When you think of Halloween pranks, you might picture harmless scares or a few well-placed fake spiders. But what happened early on November 1, 2025, at Harvard Medical School's Goldenson Building in Boston was anything but harmless. Instead, it was a serious incident involving a large commercial firework that caused an explosion, triggered a federal investigation, and led to criminal charges against two young men. This was no ordinary college prank — it was an act taken seriously by law enforcement and the courts.
The Who: Logan D. Patterson and Dominick F. Cardoza
The two men at the center of this explosive event are Logan D. Patterson, 18, from Plymouth, Massachusetts, and Dominick F. Cardoza, 20, from Bourne. Both were in the Boston area for Halloween weekend, reportedly attending parties at local colleges, including the Wentworth Institute of Technology. Their night of festivities took a dangerous turn when they allegedly decided to set off a large commercial firework inside the Goldenson Building, which houses research labs and offices for Harvard's neurobiology department.
Surveillance footage reportedly captured the pair wearing face coverings as they approached the building shortly after 2 a.m. on November 1. They were seen climbing over a chain-link fence into a construction area and then scaling scaffolding to access the roof. From there, they entered the building and allegedly ignited the firework inside a locker, causing the explosion, which occurred on the fourth floor of the Goldenson Building.
The What: A Commercial Firework Explosion
The explosion was caused by a large commercial firework, described in court documents as a cherry bomb placed inside a locker, as reported by the Associated Press. The blast triggered a fire alarm and caused a loud noise that startled people nearby. Fortunately, the building was empty at the time, and no injuries were reported. However, the incident was far from a simple noise complaint or minor property damage. The Boston Fire Department's Arson Unit ruled the explosion intentional, and the FBI quickly launched a federal investigation, as reported by PEOPLE.
The damage was limited to property, with no structural harm reported and all labs and equipment remaining intact, as reported by the Associated Press. Still, the use of an explosive device inside a prestigious academic institution raised serious concerns about safety and security.
The Where: Harvard Medical School's Goldenson Building
The Goldenson Building is part of Harvard Medical School's campus in Boston and is home to important research labs, particularly within the neurobiology department. The building was empty during the incident, which likely prevented injuries but did not lessen the gravity of the act. The fact that the explosion occurred inside a facility dedicated to scientific research and education added to the shock and seriousness of the event.
The When: Early Morning of November 1, 2025
The explosion happened between 2:25 and 2:45 a.m. on November 1, 2025, just after Halloween celebrations had wound down. The timing suggests the suspects were still out from their Halloween parties when they allegedly decided to carry out the act. Witnesses reported hearing the loud blast and seeing two individuals fleeing the scene, which prompted a swift response from campus security and local authorities.
The Why: Allegedly Intentional and Treated as a Federal Crime
Authorities have made it clear that this was no harmless prank. The FBI's Boston Division Special Agent in Charge, Ted Docks said, "Igniting an explosive device inside a school locker is not some harmless, college prank. It's selfish, short-sighted, and a federal crime," as reported by PEOPLE. The suspects were charged with conspiracy to damage property by means of fire or an explosive, a serious offense that carries potential penalties of up to five years in prison, supervised release, and hefty fines.
The suspects' motives remain unclear, but Docks told ABC News that Patterson and Cardoza allegedly boasted about their actions to friends after the fact, as reported by PEOPLE. This bragging helped authorities identify and apprehend them. Their lawyers have argued that the case is one of "significant overcharging," as reported by the Associated Press, suggesting the case involves property damage that might typically be handled at the state level rather than as a federal matter.
What You Should Know: The Broader Impact
This incident serves as a stark reminder that actions involving explosives, even if intended as pranks, carry serious consequences. The use of fireworks or any explosive device in a public or institutional setting is not only dangerous but also illegal. The federal response underscores the importance of maintaining safety and security on college campuses, especially in facilities dedicated to research and education.
For those of you who might be tempted to pull a prank, this case highlights the risks involved — not just to yourself but to others and the community at large. The legal repercussions can be severe, and the damage to property and trust can have lasting effects.
What's Next for Patterson and Cardoza?
Both men reportedly appeared in federal court in Boston shortly after their arrest. They were released pending trial but are prohibited from possessing explosives or visiting Harvard University during this period. A preliminary hearing is scheduled for November 24, 2025, where the case will continue to unfold.
Their defense attorneys have expressed confidence that the charges will be reduced or dismissed, framing the incident as a youthful mistake rather than a malicious act. However, the federal charges and the involvement of the FBI's Joint Terrorism Task Force — as announced by FBI Boston — indicate that authorities are taking this matter very seriously.
