2 Men Accused Of Causing Harvard Medical School Explosion Plead Guilty

CAMBRIDGE, MA — The two men arrested in connection to an explosion that took place at Harvard Medical School in October have pleaded guilty in federal court, according to the United States District Attorney’s Office District of Massachusetts.

Logan David Patterson, 18 and Dominique Frank Cardoza, 20, have officially pleaded guilty to one count each of conspiracy to damage, by means of an explosive. According to officials from the U.S. Attorney's Office for the District of Massachusetts, a Roman candle commercial firework was used by the two young men as the ignition for the indoor explosion that took place at approximately 2:45 a.m. on the fourth floor of the Goldenson Building at 220 Longwood Ave. on Nov. 1. Boston police conducted a sweep of the building and did not find any additional explosive devices.

The room where the explosion took place is a research laboratory as part of the school’s Department of Neurobiology. Patterson and Cardoza were reportedly captured on surveillance camera climbing over a chain-link fence into a construction area surrounding the Goldenson Building and then climbing scaffolding to access the roof.

The pair excited the facility via a first floor emergency exit, and then fled the scene in opposite directions. According to the USDA, the pair discarded clothing they were wearing during the incident and returned to Wentworth Institute of Technology where they were visiting for Halloween.

The charge provides for a sentence of up to five years in prison followed by three years of supervised release and a fine of up to $250,000. Patterson and Cardoza are scheduled to be sentenced by U.S. District Court Judge Angel Kelley on Tuesday, Aug. 4.
