BOSTON— Two Massachusetts men are facing serious charges following a dramatic explosion that rocked Harvard University's Longwood Medical Campus early Saturday morning.

According to authorities, 18-year-old Logan David Patterson from Plymouth and 20-year-old Dominick Frank Cardoza from Bourne were arrested and charged with conspiracy to damage by means of fire or an explosive. The explosive device, believed to be a large commercial firework similar to a roman candle, detonated inside a wooden locker on the fourth floor of the Goldenson Building around 2:45 AM.

Surveillance footage captured the suspects walking near the medical school shortly before the blast, where they were seen lighting what appeared to be fireworks. Just minutes later, security alarms blared as campus police were alerted to a fire alarm triggered by the explosion.

The aftermath showed no structural damage to the building, and all labs remained operational. However, investigators acted quickly, combing through evidence and security footage to identify the two culprits. Reports indicate that they discarded distinctive clothing items as they fled the scene, showcasing a clear awareness of being caught on camera.

Witnesses in the vicinity reported hearing two explosions about five minutes apart, raising concerns among the community. Thankfully, there were no injuries linked to this reckless act, but the incident has sent shockwaves through Boston's academic circles.

Following the release of the suspects' images, members of the public bravely stepped forward to identify Patterson and Cardoza, leading to their swift apprehension. Officials emphasized the extensive resources that were mobilized to ensure there was no ongoing threat to the public.

As the investigation continues, there will be an increased police presence at the Longwood campus, underscoring the seriousness of this alarming case. Authorities want to reassure the community that this incident has been contained and there is no further threat to public safety.
