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.

16-year-old Khyon Smith-Tate found shot to death inside Chipotle bathroom on edge of Temple University’s campus in North Philadelphia
PHILADELPHIA — A 16-year-old boy was fatally shot inside the bathroom of a Chipotle restaurant near Temple University’s campus in North Philadelphia on Monday afternoon, police said, as students and staff returned for the first day of the Spring 2026 semester.
The shooting occurred at approximately 5:00 p.m. inside the Chipotle located in the 1100 block of West Montgomery Avenue, on the ground floor of The View at Montgomery apartment complex. The building is situated near Temple University’s Student Center and TECH Center.
Police later identified the victim as Khyon Smith-Tate, a North Philadelphia resident. Philadelphia Police Chief Inspector Scott Small said Smith-Tate was found with a gunshot wound to the chest and was pronounced dead at 5:24 p.m.
Temple University President John Fry and Vice President for Public Safety and Chief of Police Jennifer Griffin issued a joint statement following the incident:
“The loss of life to gun violence is a profound tragedy, and there are no words that can make sense of it. Our thoughts are with the victim’s family and loved ones.”
According to investigators, Smith-Tate and another minor entered the restaurant and requested access to the restroom. Chief Inspector Small said the shooting is believed to have occurred inside the bathroom.
Moments later, employees discovered Smith-Tate suffering from a gunshot wound. Police recovered one spent shell casing from a semiautomatic weapon inside the restroom.
Although the victim’s last known address was approximately eight blocks from the scene, authorities have not indicated what brought him to the location or what led to the shooting.
At the time of the incident, the restaurant was crowded, and multiple individuals inside the business were detained briefly for questioning. However, police said they have not yet obtained any statements from witnesses who reported hearing a gunshot.
A person of interest was taken into custody several blocks from the scene shortly after the shooting, but Chief Inspector Small said that individual’s involvement remains unclear.
As of Tuesday, police confirmed that no arrests have been made and no motive has been established.
Investigators believe Smith-Tate entered the restroom with another minor, though the whereabouts of that individual remain unknown.
Police are also seeking information about three possible suspects, described as teenagers carrying backpacks.
Chief Inspector Small noted that the area is equipped with numerous surveillance cameras, which detectives are reviewing as part of the ongoing investigation.
Authorities are asking anyone with information related to the incident to contact the Philadelphia Police Department.
