Logan David Patterson and Dominick Frank Cardoza Arrested in Connection with Explosion at Harvard Medical School
BOSTON, MA — Federal authorities have arrested two Massachusetts men in connection with an explosion that occurred over the weekend at Harvard Medical School’s Goldenson Building.
According to officials, Logan David Patterson, 18, of Plymouth, and Dominick Frank Cardoza, 20, of Bourne, were taken into custody on Tuesday morning. Both men have been charged with conspiracy to damage property by means of fire or an explosive and were scheduled to be arraigned in federal court later in the day.
The incident took place early Saturday morning inside the Goldenson Building, located on the Harvard Medical School campus in Boston’s Longwood Medical Area. The facility houses research laboratories and offices for the school’s Department of Neurobiology. Authorities confirmed that no injuries were reported as a result of the blast.
At a press briefing, U.S. Attorney Leah B. Foley addressed public concerns following the revelation that the explosion was intentionally caused.
“Anxiety levels naturally rise when the public learns that an explosion was intentionally caused. I would say those levels may rise even higher in the Boston area,” Foley said. “However, based on current findings, there is no ongoing threat to Harvard University or the surrounding community.”
According to the criminal complaint, surveillance footage and witness statements linked Patterson and Cardoza to the scene. The pair had reportedly been in Boston for Halloween festivities, including events at nearby colleges such as Wentworth Institute of Technology.
On the day of the explosion, surveillance video captured the suspects walking toward the Harvard Medical School complex. Witnesses told investigators that the men selected the Goldenson Building because it “appeared abandoned” and gained access through the roof.
The charging documents allege that the suspects ignited a roman candle outside the facility before placing a cherry bomb inside a locker on the fourth floor. The device later detonated, triggering a fire alarm and prompting a response from university and city police.
“Let me be clear,” said Ted Docks, Special Agent in Charge of the FBI’s Boston Field Office. “Setting off an explosive device inside a locker at an institution dedicated to education and research is not a prank — it’s reckless, it’s dangerous, and it’s a federal crime.”
Neither Foley nor Docks commented on a possible motive, citing the ongoing investigation.
Harvard Medical School officials reported that the blast caused no structural damage, and all laboratory equipment and research materials remained intact. The Boston Fire Department confirmed that the explosion was intentional, and a thorough search of the building revealed no additional explosive devices.
University police stated that an officer responding to the fire alarm observed two individuals fleeing the building shortly after the explosion occurred — a detail that later contributed to identifying the suspects.
Federal investigators, including members of the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), continue to examine the case. Additional charges may be filed pending the outcome of forensic and investigative reviews.

Venezuelan national Julio Cesar Sosa-Celis shot in the leg by an immigration agent in Minneapolis
On January 14, 2025, federal law enforcement personnel were engaged in a targeted enforcement operation involving Julio Cesar Sosa-Celis, a Venezuelan national who has been present in the United States since 2022.
The operation escalated into a high-speed pursuit, a physical confrontation, and an ambush by multiple subjects, necessitating the use of a defensive firearm discharge by a federal agent.
At approximately 6:50 PM, federal officers initiated a targeted traffic stop of a vehicle operated by Sosa-Celis.
The subject refused to comply with law enforcement commands and attempted to flee the scene.
During the pursuit, the subject’s vehicle collided with a stationary, parked car.
Following the collision, the subject abandoned the vehicle and fled the scene on foot.
A federal agent pursued the suspect on foot and successfully intercepted him. As the agent attempted to effect an arrest, the subject became combative, resulting in a violent struggle on the ground.
During this confrontation, two additional male subjects emerged from a nearby residence to intervene.
These individuals reportedly ambushed the agent, utilizing a snow shovel and a broom handle to strike the officer.
The situation escalated when the primary suspect, Sosa-Celis, regained his footing and joined the two additional subjects in the assault.
Reports indicate the suspect struck the agent with a blunt object (identified as either the shovel or broom handle).
Citing an immediate threat to his life while being outnumbered and actively assaulted by three individuals, the agent discharged his service weapon in self-defense.
The discharge struck Sosa-Celis in the lower extremity (leg). Following the shot, all three suspects retreated into a nearby apartment complex and initiated a barricade situation.
Following a brief standoff, U.S. Immigration and Customs Enforcement (ICE) successfully secured the perimeter and apprehended all three individuals without further injury.
Both the federal agent and Sosa-Celis were transported to a local medical facility for treatment.
Images from the scene showed Sosa-Celis conscious and alert during transport.
All three subjects involved in the assault are currently in the custody of ICE.
Further charges related to the assault on a federal officer and resisting arrest are pending review by the U.S. Attorney’s Office.
