Police on Long Island seized a massive arsenal of assault rifles and thousands of rounds of ammunition during a search of a man's Patchogue home. The man was attempting to illegally sell the weapons out of his home, authorities said.

Suffolk County District Attorney Timothy Sini said Thursday the seizure has put an end to "a recipe for a massacre." Police seized 48 guns from the suspect's home, including four illegal assault rifles.

Police also seized 18 metal ammunition cans filled with ammunition, 50 large-capacity magazines, armor-piercing bullets and an assortment of illegal knives.

"This case is an extraordinary example of superb collaboration between the Suffolk County Police Department and the Suffolk County District Attorney's Office," Sini said. "Because of that collaboration, we put an end to a recipe for a massacre."

Before becoming DA in January, Sini served as the Suffolk County police commissioner.


Police arrested Larry Guerrieri, 65, on February 21, 2018, after they searched his home. Cops raided his home after Guerrieri attempted to sell an illegal assault rifle to an undercover officer in January, police said.

Guerrieri was arraigned Thursday on charges of criminal possession of a weapon in the second degree, criminal sale of a firearm in the third degree, and three counts of criminal possession of a weapon in the third degree, authorities said. Judge Gaetan Lozito set bail at $250,000 cash or $500,000 bond.

"Based on the evidence we've collected thus far, these guns, if not seized as a result of this investigation, could have flooded the streets of Suffolk County," Sini said. "These are killing machines, and they were in the hands of an individual who was selling these weapons illegally."
