Two Men Plead Guilty In Harvard Medical School Lab Explosion Case
Two men, Logan David Patterson and Dominick Frank Cardoza, pleaded guilty Friday in federal court to charges tied to a fireworks explosion inside a Harvard Medical School laboratory, the New York Times reported.
The plea followed an FBI Boston Joint Terrorism Task Force investigation that led to their arrests and federal charges, and prosecutors characterized the blast as a serious federal crime rather than a harmless prank.
The episode traces back to an explosion inside a building at Harvard Medical School that prompted campus and federal responders to secure the scene. Harvard said there was no structural damage, all labs and equipment remained intact, and cleaning was completed so research could resume. Social posts ranged from calls to treat the act as terrorism to others saying it was not politically motivated but the reckless act of teenage football players.
With guilty pleas entered, the case moves to sentencing in federal court and public debate continues over accountability for dangerous stunts on campus.
