BOSTON – A Holliston man was sentenced today in federal court in Boston for unlawful possession of ammunition after a substantial weapons trove was uncovered during a search of his home. 


Joseph Gargiulo, 41, was sentenced by U.S. Senior District Court Judge Douglas P. Woodlock to time served (approximately 14 months), pending acceptance by and entrance into an intensive mental health inpatient treatment facility. Once placed in a treatment facility, Gargiulo will be on supervised release for three years.  In July 2017, Gargiulo pleaded guilty to one count of possession of ammunition by a prohibited person.  Gargiulo was prohibited from possessing firearms and ammunition due to an active restraining order issued against him in Wrentham District Court.


On July 27, 2016, agents received information that Gargiulo had acquired parts to make an AR-15 rifle and that he was stockpiling other weapons, including tasers, mace guns, hunting knives and incendiary chemicals.  Around the same time, Gargiulo stated that he “will plant bombs in police stations…and kill as many homeland security officers as he can before they kill him.”  Further investigation revealed that Gargiulo had stated that he wanted to attack a mosque and/or kill President Obama.  Gargiulo said he wanted to “chain a mosque closed and burn it down,” but he never mentioned a specific mosque or time for such an attack.


A search of Gargiulo’s residence resulted in the seizure of parts needed to assemble an AR-15 rifle, over 250 rounds of ammunition for an AR-15 rifle, over 100 rounds of nine millimeter ammunition, chemicals that could be combined to create incendiary or explosive compounds, and hand written notes threatening violence against members of the Islamic faith.


Acting United States Attorney William D. Weinreb; Harold H. Shaw, Special Agent in Charge of the Federal Bureau of Investigation, Boston Field Division; Mickey D. Leadingham, Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms & Explosives, Boston Field Division; Colonel Richard D. McKeon, Superintendent of the Massachusetts State Police; Holliston Police Chief Matthew Stone; and Medway Police Chief Allen M. Tingley made the announcement today.  Assistant U.S. Attorney Mark Grady of Weinreb’s Criminal Division prosecuted the case.
